When one is Monkey Railing (ie. Defecating into one's own mouth with a continuous and uninterrupted log) and accidentally hits the gag reflex such that a total exchange of stomach contents for rectal contents occurs.
Oh man, I was monkey railing the other day and I totally just quatchi'd into my buttox.

Bitch, to act or become someone's a bitch.

A reference to the 2010 Olympic mascot, this hairy fucker had a habit of brushing off adults and children alike. Possibly because he was the most popular or the largest of the mascots, his ego and attitude served his name well.
"Johnny, can I have a turn at the Xbox please?
- "Shut up Pete, I'm still playin'."
"Pleeeaasssee? I've been waiting for hours!!!"
- "Fuck Pete, quit being such a Quatchi!"

Albert took the last donut. That was such a Quatchi move.

After Fredrick's arrest and conviction, everyone knew that pretty face of his would make him someone's Quatchi on the inside.

Short for Pasquatchi... the hairy area around a womens genitals, aka her bush. Only considered a true quatchi if it is large, sometimes engulfing her thighs, has a distinct odor and is generally unkept.
Man, I took home this chick the other night and when she slipped out of her dress I saw she had the biggest, furriest, brightest fire engine red quatchi I had ever seen... I could smell it from across the room.

A large unshaven and itchy beaver. You can see the unusually hairy legs that sprout from the bottom but the rest of the body is covered in an unnatural fur. The smell of the Quatchy is immediately recognizable to resemble fish that has been left on a hot sunny beach for a few weeks. This is a shy beast, possibly lending to the fact that being so hairy and pungent, it never gets any kind of social interaction...
Dude... check out Quatchi... chick needs to bath more.... or at least shave...
