1. Crabs
   Cooties
2. Mozzies
   Skeeters

Although "cooties" would evolve into a perennially popular schoolyard term for an imaginary germ, the word was originally applied to body lice by British soldiers in World War I. The term's history is uncertain, but it possibly references the coot, an aquatic bird that is a notorious carrier of lice.

1. Fire water
   Loudmouth soup
2. Giggle water

1. Foul ball
   Bad billiards
2. Dirty pool
   Tricky tennis

Dirty pool first came into use in 1918. In this usage, the word pool is derived from the French word "poule," meaning "hen."

1. Hot dogs
   Pup tails
2. Growlers

   Kitsch
2. Schmutz
   Schlep

First appearing in print in 1915, schlock is derived from the Yiddish word "shlak," which itself originates from the German "schlacke" meaning "dregs" or "scum." A synonym for trash, schlock is most often used today to describe low-quality films and entertainment.

   Mesmerist
2. Svengali

1. Femme fatale
   Maneater
2. Floozy
   Vamp

This word for a dangerously flirty seductress is derived (obviously) from the familiar vampire. The vamp was a popular stock character in early cinema. It was possibly first applied to the popular silent-era actress Theda Bara for her role as "The Vampire" in the 1915 film "A Fool There Was."

1. Ah, applesauce!
   What a bunch of bananas!

   Jazz hop
2. Rent party
   Cash bash

2. Dazzler
   Stunner

Used to describe something unique or extraordinary, "doozy" has been long thought to have been derived from the Duesenberg Motor Company, an American car manufacturer founded in 1916. Nevertheless, there is evidence that the word predates the car company and is more likely a corruption of daisy.

1. Dewdropper
   Flapper
2. Doughboy

1. The goat's spectacles
   The fish's bicycle
2. The bear's bolar

The years after the First World War through the 1920s brought a plethora of faddish animal phrases used to describe excellence or outstanding qualities. These fun non-sequiturs included "the bee's knees," "the monkey's eyebrows" and many others. "The cat's pajamas" is among the most enduring of these.

1. Gad about
   Chew the rag
2. Take a ride
   Horse around

The idiom "horsing around" first appears in print in 1919 and is likely related to the much older horseplay. Although horseplay generally refers to roughhousing or rowdy play, "to horse around" describes silly, joking behavior one indulges in to avoid work.

1. Cushy

1. Cabin fever
   Space madness
2. Closet lunacy
   Shack shivers

Although movies, TV and popular fiction present cabin fever as a form of insanity that often ends with a murderous rampage, it's much more akin to a simple case of the blues. A person with cabin fever is probably too listless to pick up an ax.

1. For Pete's sake!
   Gosh darn it!
2. Great Caesar's ghost!
   Hot spit and monkey vomit!

"For Pete's Sake" is a prime example of a minced oath, the euphemistic substitution of a mild word for an objectionable one in an exclamatory phrase. Why is Pete standing in for God? Although there is no concrete evidence, some sources say the name references St. Peter.

1. Shut your crump hole!
   Cease the flap!
2. Tamp your pipe!
   Put a sock in it!

1. Crabby
   Grouchy
2. Grumpy
