After the argument, she kept her coworker at arm’s length to avoid more drama.

Remember that friend-of-a-friend you’re not so sure about? The one you’d rather not let get too close? That’s someone you keep "at arm’s length." This common phrase comes from the old practice of measuring distances with body parts (not so old, really; we still measure in feet), and an early version even shows up in Shakespeare’s 1599 play As You Like It, where the line goes: "Hold death awhile at arm’s end."

When my car broke down, a kind stranger stopped to lend me a hand.

Many expressions we use figuratively today started out in very literal situations. That’s the case with "to lend a hand," which originally referred to physically using your hands to help someone with a task. Over time, the meaning expanded, and the phrase can now be used for any kind of help.

His birthday is on the tip of my tongue… wait, is it next Thursday?

You’re chatting with your best friend, remembering old times, when a familiar song pops into your head. You remember the lyrics perfectly, but who was the singer? Ahh… It’s on the "tip of your tongue"! Used in English since the 16th century, this idiom describes those moments when something feels just within reach but doesn’t fully come to mind.

Ever since they met, he’s been head over heels for her.

When was the last time you were completely captivated by someone or something? In those moments, you could say you were "head over heels." The phrase dates back to 14th- and 15th-century English as "heels over head," originally describing literal upside-down movements. Over time, it evolved into its modern form, describing the feeling of being madly in love.

I’d give my eye teeth to get tickets to that concert!

In the past, canines (often called eye teeth because they sit just below the eyes) were among the most important teeth. Losing one was a big deal, which likely explains the origin of this idiom. It’s still used today to describe a major sacrifice or something someone desperately wants.

I bet your ears are burning after that email went around the office.

It turns out your ears can "burn" even when there’s no infection. This kind of burning has a different interpretation: it means someone is talking about you behind your back. It’s not always negative, but it does involve gossip. The idiom comes from ancient beliefs that physical sensations in the body could indicate external events.

Renovating the old house is going to cost us an arm and a leg.

When something costs an arm and a leg, it means it’s extremely expensive or requires a big sacrifice. There are two main theories about its origin: one, now widely regarded as a myth, suggests that in the 15th century, artists charged more if a portrait included the subject’s arms or legs. The other theory links the phrase to the serious physical sacrifices soldiers can make in war.

Break a leg at the competition; everyone’s rooting for you.

When you tell your singer friend to "break a leg," you’re not wishing them anything bad; in fact, it’s the opposite. This idiom comes from old theater superstitions, where saying "good luck" was thought to bring exactly the contrary. To avoid tempting fate, people would say something negative to actually wish someone something positive.

He cried his heart out after saying goodbye to his childhood home.

Since ancient times, people have believed that the heart is where emotions live. So when you "cry your heart out," you’re letting out all your feelings, often very intensely. The phrase usually reflects pain, sadness, ordeep emotional suffering.

Even though we argued, he’s still my flesh and blood, and I’ll always protect him.

This idiom is much less creepy than it might sound at first. To be someone’s "flesh and blood" means you are part of their family, or are treated as if you were. Some sources trace one of the earliest uses of this phrase to an Old English translation of the Bible, specifically in Matthew 16:17.

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.
