Military lingo

10 military terms that made it to the civilian vocabulary

Our everyday vocabulary is littered with terms, phrases, idioms, and concepts drawn from different contexts—such as medicine, science, sports, politics, etc.—often altered or reinterpreted. The military world is no exception, and every day we use phrases that originated in war contexts or that were popularized by soldiers. Let’s have a look at some examples!

One of the most widespread phrases popularized by military use, this acronym originated not in the armed forces but in the dental hygiene field as part of a list of recommended abbreviations for secretaries. However, it was adopted by the military around the 1950s and widely used during the Korean War. While it was conceived to mean "as soon as practically possible", its use in the military context shifted its meaning to "immediately".

Have you ever described an ambiguous or unclear situation as "no man’s land"? Well, that phrase was initially used for actual land, and it is still used that way. Popularized during WWI as a descriptor of the barren land between opposing trenches, it had been in use for centuries for unoccupied or unclaimed wastelands, often in dispute among bordering jurisdictions. While we now often use it figuratively, it is used in its literal sense in conflict zones and territorial disputes.

Our modern life is hectic and filled with deadlines, but these, although important, don’t usually pose a threat to our lives. The original deadlines, though, were a different story. The phrase emerged during the American Civil War, and it referred to the boundary lines drawn around prisoner camps. Any prisoner who crossed the line was instantly shot, effectively making it a ‘deadline’. Luckily for us, its meaning has shifted to reflect a time limit.

If you ever wondered about the connection between coffee and someone named Joe, several theories claim to have the answer. The most popular one —although refuted by many historians— links it to Josephus "Joe" Daniels, famous for banning alcohol in the Navy, which allegedly popularized coffee as a substitute. A more likely theory points to the term ‘jamoke’ (a contraction of java + mocha), widely used in the military around the 1930s.

The color blue has traditionally been associated with melancholy, but military men might have had a hand in popularizing this idiom. Though blue flags currently carry a different meaning in nautical terminology, they were once used as a sign of mourning. If a ship’s captain or other high-ranking officer died at sea, their ship would fly a blue flag and paint a blue band around the hull, a custom that intertwined the color blue with sadness.

If we think about it, most of the time we say someone’s AWOL, a leave is not required. We are simply stating that we don’t know where they are or why they left. But the case is quite different for its military use. First recorded in the 18th century, it was used as a full phrase, although it eventually became an initialism around WWI and then an acronym around WWII. Still in use in the military, it carries a more dire meaning than in the civilian context.

"Anything that can go wrong will go wrong." All of us have invoked Murphy’s law at some point in our lives, but who’s Murphy? The answer takes us to a U.S. Air Force base and a series of rocket tests during the late 1940s. After several mishaps, aerospace engineer Edward A. Murphy famously exclaimed: "If there are two or more ways to do something and one of those results in a catastrophe, then someone will do it that way." Murphy’s frustration was later summarized at a conference as "Anything that can go wrong will go wrong", and the rest is history.

Most people wouldn’t be surprised to learn that this phrase is of military origin, but not many would be able to explain how it came to mean ‘understood’. During WWII, the American and British forces used the Able-Baker alphabet for radio communications, where Roger (and not Romeo) represented the R. ‘Roger’ meant your message had been received and understood. While most militaries later shifted to the NATO alphabet, the use of roger as ‘understood’ stuck and was popularized by its use in the Apollo lunar missions.

While not as commonly used as other phrases of military origin, most people know that if someone tells them "I got your six," it means they have their back. The phrase stems from WWI aviators using the 12-hour clock face to describe directions: 12 o’clock was the front, 6 o’clock the back, and 3 and 9 o’clock the sides. As a blind spot, the back was a pilot’s most vulnerable area, so a wingman who ‘got their six’ was always appreciated.

People telling a story about rambunctious children running amok would hardly imagine that this phrase has quite the violent origin. In Malay and Javanese cultures, amuk was used to describe warriors who launched frantic and violent attacks, often associated with a spiritual possession. The term was introduced into English by 16th-century European explorers, but it was Captain James Cook who popularized the phrase "run amok."

Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.
