Get a mullet up ya

A yesteryear saying from the late 1980's used by the average down to earth Aussie bloke, generally around the pub whilst heavily intoxicated. It can be either used as an insult or term of endearment depending on the situation it is said in.
A modified version can also be used for upper class persons:- one should take a mullay and insert it up oneself.
