a Swissie
Sticking a ping pong bat up a guy's butt and making him whack his nuts with it. Only Swissies do this. It's a national sport.
I saw a Swissie in the park doing it to a guy in a suit. The guy cried like a baby.
My cousin went to Switzerland and came back with a broken nose from a Swissie.
My teacher said if we didn't behave, she'd turn into a Swissie and whack our nuts.
