I love dictionaries of all stripes, and this collection of slang from 1920s America proves why. We need to bring some of these terms back, and how!
My faves:
Chassis – the female body
Fire extinguisher – a chaperone
Giggle Water – An intoxicating beverage; alcohol
Hayburner – (1) a gas guzzling car
Spifflicated – Drunk.
