A game usually played in the armed forces. A group of males sit around in a circle and masturbate, to see who ejaculates last. The last one to ejaculate has to eat the biscuit, complete with salty topping.
Anyone for a game of Spunk Biscuit... Naah Fuck that I had a wank before I came out you'll kick my arse... Besides I've already had lunch.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
