Old-Time Expressions

"The bee's knees" became popular in the 1920s flapper era and means something or someone outstanding or excellent. It was part of a trend of nonsense phrases like "the cat's pajamas" and "the cat's meow" that all meant the same thing — the height of excellence.

"Don't take any wooden nickels" dates back to the early 1900s and was a lighthearted way of saying "be careful" or "don't let anyone swindle you." It was commonly used as a parting phrase, similar to "take care of yourself."

A "wet blanket" is a person who spoils other people's fun or enthusiasm. The expression dates to the early 1800s and comes from the practice of using a wet blanket to smother a fire — just as the person smothers the enjoyment of others.

"23 skidoo" was one of the first widespread slang expressions in America, popular from around 1906. It means to leave quickly, scram, or get going. Its exact origin is debated, but it was so popular that it became a catchphrase of the early 20th century.

"The cat's pajamas" originated in the 1920s and means something excellent or superlative. Coined during the Jazz Age, it was part of a fad of combining animal names with human clothing or body parts to describe something outstanding, alongside "the bee's knees" and "the cat's meow."

"Knows his onions" was 1920s slang meaning someone is very knowledgeable or well-informed about a particular subject. Some etymologists believe it may reference S.G. Onions, a British lexicographer, though this is debated. Similar expressions included "knows his stuff" and "knows his beans."

"Burning the midnight oil" means staying up late to work or study. The expression dates back to the 1600s, when people literally burned oil in lamps to see after dark. It was widely used through the 20th century and remains in use today.

A "drugstore cowboy" was 1920s–1930s slang for a man who hung around drugstores, street corners, or other public places trying to pick up women, rather than doing honest work. The term implied someone who dressed sharply but was all style and no substance.

"Getting the sack" means being dismissed from employment. The expression may date back to the days when tradesmen carried their own tools in a sack — when an employer handed you your sack, it meant your services were no longer needed. It was common parlance throughout the 20th century.

A "fuddy-duddy" is a person who is old-fashioned, overly conservative, or fussy. The term appeared in the early 1900s and was widely used by the mid-20th century. Its exact origin is uncertain, but it may come from the Scottish word "duddy" meaning ragged or shabby.

"Sold down the river" has a painful origin: it referred to enslaved people in the Upper South being sold to plantations further down the Mississippi River, where conditions were often far more brutal. By the mid-20th century, it came to broadly mean being betrayed or cheated by someone you trusted.

"On the lam" means running away or fleeing, especially from law enforcement. The expression became popular in the late 1800s and early 1900s. "Lam" likely comes from the Scandinavian word "lamja," meaning to beat or thrash — the idea being to "beat it" or run away quickly.

A "gadabout" is a person who goes from place to place in search of amusement or social activity. The word dates to the early 1800s, combining "gad" (to roam or wander) with "about." It was commonly used through the mid-20th century, often with a mildly disapproving tone.

"Fly off the handle" means to suddenly lose one's temper. The expression dates to the 1800s American frontier and comes from the real danger of axe heads flying off their handles during chopping — a sudden, uncontrolled, and potentially dangerous event, much like an outburst of anger.

"In cahoots" means to be conspiring or working together secretly, often for dishonest purposes. The word "cahoot" appeared in American English in the early 1800s, possibly derived from the French "cahute" meaning a small hut or cabin — suggesting people huddled together in secret.
