10 Slang Phrases From the ’40s and ’50s That Will Make You Sound Old

Slang from the ’40s and ’50s were playful, inventive & charming. There were these colorful expressions for everyday things, and it was part of the culture then. Some of these words are long gone, but they will still make us smile when we hear them today. But if you use them now, it sounds like you were born in another century. Let’s take a look at 10 slang terms from the ’40s and ’50s that will make you sound a bit retro.

“Daddy-O”

This was a cool way to describe someone, specifically a man, in those days. It was favored by jazz fans or hipsters in the ’40s and ’50s. Now, “Daddy-O” is likely to get young people laughing or scratching their heads and asking what it is. The term formerly applied to a hipster or stylish person – but now it sounds like a blast from the past and a link to a time of swing bands and fountain drinks.

“Bee’s Knees”

To refer to something as the “bee’s knees” meant that it was great or excellent. This was a catchy phrase to show excitement about something you enjoyed. It is old and strange now, because few people would compare greatness to a bee’s anatomy. It’s a sweet throwback, however, to simpler days when slang was fun.

“Knuckle Sandwich”

This was a bright and colorful phrase for punching somebody. It was generally used jokingly or in a semi-serious context, such as in old movies or cartoons. ” Do you want a knuckle sandwich?” now sounds silly or dramatic because people no longer use this kind of playful threat.

“Hubba Hubba”

This was a term to compliment someone beautiful. You heard it in the movies, or from young people, if they saw a good-looking person. Today “Hubba hubba” would likely get you more laughed at than being taken seriously. It’s an expression very much out of fashion.

“Cool Cat”

A “cool cat” was a person who was sleek, fashionable or in the know, especially in jazz circles. It was a compliment then. It is now clichéd and could seem like making too much of an effort at sounding retro. Being a “cool cat” doesn’t expire, even if the term does.

“Flip Your Wig”

When someone said this, this meant they were very excited or shocked. It was a playful expression to describe an extreme reaction. It’s a word that could get someone confused these days if they didn’t know ’50s talk. The phrase recalls an era when language was colored and full of character.

“Big Tick”

This word referred to something wonderful or fantastic. Saying something was a “big tick” was an expression of excitement. But modern listeners may not recognize the reference and might miss it. It’s one of those phrases that hasn’t aged so well – but it’s still a special one.

“Ankle-Biter”

The term was applied to small children, often wryly or affectionately. It created an amusing scenario of children running around & creating chaos. Some still do it but it’s less widespread and old-fashioned — especially to children.

“Gas”

If something was “gas,” then it was lots of fun. People used it to describe parties, music, anything exciting. If you say this now, it sounds like you were walking off the set of a black-and-white movie. The meaning is obvious, but the phrase seems specific to a historical moment.

“Made in the Shade”

This phrase meant that someone had it easy or was set up for success. It was a sure sign that all was well. It would be confusing today to someone not familiar with older slang. It’s a line that conveys how language changes with time, even when the sentiment remains the same.
