Aussie Slang. The act of doing a poo while mooning someone.
The guy was shocked when the girl started to moon him, but even more so when it turned into a poon!

A Poon is approximately 10 milliliters of muc (aka cum, semen, wacky liquid, knuckle children, funny hose leakage, 500 grand of dept, the wormies, liquid dream killer...). One poon of muc is enough to perfectly fill one lightbulb casing.
Oh my god, a new record, 17 whole poons of muc in one ejaculation.
I'm about to muc, get ready to catch my poons.
This hot rod can hold 45 poons worth of muc.
