A game developed in the early 2000's in Sheffield, England that involves a foam baseball bat and a sofa. The idea of the game is to jump into the sofa with the baseball bat and make the loudest noise possible whilst still in the air. The strike on the sofa must be completed before any part of the body touches the sofa. The winner is the competitor who produces the loudest noise

The name of the game originated from 'whamming' the sofa with the foam bat
Fancy a game of Whammage?

Sure. Hope we don't wake anyone up!!

Get the Whammage mug.
Lettuce that has been cooked until it becomes a wet, sloppy, relatively dense, algae like substance. Originally discovered when lettuce was added to toasted sandwiches by Adelaide stoners suffering from the munchies in the mid '90s. A toasted sandwich containing lettuce is known as a Wammage Sammage.
DON'T put lettuce in that stir-fry you loon! You'll end up with Whammage!!!
