Shilly

When someone has a perplexingly small penis and is an easier way of saying someone has a short willy

Foreskin balloon

When your fucking a girl (or man) up the ass and they fart on your dick and it blows up your foreskin.

“Hey bro Libby give me a fucking foreskin balloon yesterday it was totally rad!”
