boofed onion

The smell of urine that has been sitting and becomes rancid over time.

That room smells like boofed onions because Timmy doesn't clean the urine on his bed.

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!"

bum onion

An unfortunate protrusion from the "chocolate starfish" AKA Farmer, Nobby etc. Can be treated with Preparation H, or a similar pharmaceutical product.

"Oooof! These bum onions give me hell when I ride my bicycle": Attributed to J Sheehan 2004

Emperor's Onion

A stink so bad it makes the paint on the walls peel, like an onion makes your eyes water.

Adam (Gets out of the washroom) - Aw man
Frank - Choke another donkey?
Adam - Nope, dropped me an Emperor's Onion for the next guy..

Double Onion

The process of having sexual intercourse where both participants are crying. Can be applied as a Triple Onion if a threesome is being partaken and so on. A Single onion is the most common.

"Hey man, heard you got lucky last night! How was it?"
"Turned into a bit of a Double Onion but It was still magical."

The Weird Onion

Unique sexual fetish in which the male inserts a peeled onion into the vagina of the female whilst forcing the peelings into her nose. The pleasure is often derived from the extreme tingling sensation within the nasal cavity

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

stuffed onion

A stuffed onion is a booty so round and tight that it brings tears to your eyes

I am not fundamentally opposed to junk in the trunk, although my preference is a stuffed onion over an oozing pumpkin.
