Spunk Biscuit 

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.

Skunk biscuit

Similar to a shart, this happens when you think you need to fart, but a small biscuit of poo tags along AND leaves a dark streak on your underwear. Named for its smell, color pattern, and general consistency. These are common among older people who have lost control of their sphincter.

(Clinching butt cheeks together while walking stiff legged) Oh, shoot! I'm gonna need a bathroom right quick, I've got a skunk biscuit here. These Wednesday undies are definitely going in the trash.
