Stiff Piston

An uncontrollable erection which lasts for a long period of time, despite attempts to flaccidate.

That girl kept staring at my Stiff Piston, it was so embarassing

Bored stiff

When a guy is so bored he starts talking to girls to fuck.

Jeff "Fuck dude i'm bored stiff!"
Amy"Awh yeah wanna come over?"

*Jeff goes to Amy's house and uses his stiffy on her*

Stiff Meat

Frozen dead animal.

The hard genital organ of a male.

Also the name of the most rockin' band Melbourne ever produced (R.I.P).

Stiff Meat rocked really hard, that's why all those girls are lining up on there knees over there! Anyone for some sausages? I'll just have to defrost them!

going stiff

Something like the poop shuffle, going stiff is a tightening of all muscles in body to keep the shit held in your arse until you have reached the toilet, you can easily identify when someone is going stiff as they look like they are waddling very quickly while walking.

Hey Greg, what's wrong? Going stiff are you?
