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!

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.
