Australian Plumber 

A sexual act where 2 men get into a 69 position and blow really hard down each other's assholes.

Originates from the fact it was first performed by an Australian and an Italian.

Matt: Hey, wanna make out?
Dan: Wash your mouth first, remember we just did the Australian Plumber.

Australian Plumber 

When a man performs cunnilingus on a woman while doing the limbo dance pose.

- Have you seen Lopes do an Australian Plumber in the men's bathroom on that drunk girl at Gonçalo's wedding?
- Yeah ahah, the man is a limbo master!
