The Weird Onion

Bro! Me and this chick from the club did the weird onion last night *high five*

Mule Onion

A reference to a woman's backside - specifically a really well-formed one. So called because, as we all know, crossing a mule and an onion results in "an ass that'll bring tears to your eyes".

"Damn, look at the mule onion on that one!"
