How to use 1920s slang at a party

Slang is a costume for your voice. Like a costume, a little goes a long way.

  1. Pick three words and wear them out. "Swell", "applesauce" and "the bee's knees" will carry a whole evening.
  2. Use it to react, not to explain. "Applesauce!" works when someone tells an obvious lie. A long sentence of slang just loses people.
  3. Put the cheat sheet where people stand. On the bar, by the food, in the bathroom. Guests pick words up through the night.
  4. Give a prize. "Best Slang" or "Best Accent" at the end makes people try.
  5. Match the slang to the character. A gangster says "gat" and "bump off"; a society heiress says "ritzy" and "the cat's pajamas"; a detective says "flatfoot" and "sing".

At a murder mystery party, slang does a second job: it makes accusations fun. A few lines to borrow:

  • "Don't hand me that applesauce. I saw you by the office at ten."
  • "Somebody here bumped him off, and it wasn't the band."
  • "If you know who did it, it's time to sing."
  • "I'm no stool pigeon, but ask the bartender where he was."

Use them in a 1920s murder mystery

If you are hosting a 1920s party, slang is half of the fun, and a murder mystery gives everyone a reason to use it. For the rest of the night, see 1920s food and cocktails and roaring 20s party decorations, and for outfits our costume ideas.

With Sleuth Night

Death at the Speakeasy is our 1920s murder mystery. It is Chicago in 1927, and Vinnie Marlowe, owner of The Velvet Hour, is found poisoned in his office during a fake police raid. It plays 6 to 16 guests, from the headline singer to the bootlegger, the off-duty cop and the rival club owner. It runs about two hours: three rounds of 20 to 30 minutes, then the vote and the reveal. Each guest gets a private link with their character and a costume suggestion, the clues show on your TV, and the host plays too. Setting up is free and you pay $29 when you press Start Round 1. Hosting 16 players or a 1920s birthday? Those pages have the details.

Questions hosts ask

What are some popular 1920s slang words?

The bee's knees and the cat's pajamas (excellent), applesauce and horsefeathers (nonsense), giggle water and hooch (alcohol), speakeasy and juice joint (an illegal bar), and swell (great).

What does the bee's knees mean?

Excellent, the best of something. It is one of the best-known pieces of 1920s slang, along with the cat's pajamas and the cat's meow, which mean the same thing.

What is 1920s slang for money?

Dough or clams for money in general, a fin for a five-dollar bill, a sawbuck for a ten and a C-note for a hundred.

What did 1920s gangsters call a gun?

A gat. A hired gunman was a torpedo, to kill someone was to bump them off or take them for a ride, and an informer was a stool pigeon.

How do I use 1920s slang at a party without overdoing it?

Pick three or four words and use them often. One "applesauce!" lands better than a sentence of ten slang words nobody follows.
