Yuck-and-chuck

The process of going through one's refrigerator and throwing out expired or gross food items. In other words, any item that makes you say "yuck" when you open it gets chucked in the garbage.

I better go yuck-and-chuck the fridge; I think the mayonnaise has become sentient.

Yuck Chuck

To violently vomit up all your stomach contents in an inconvenient manner.

"Hey man, pull over I'm gonna yuck chuck!"

"Yuck chuck? The hell is that? I'm not pulling over."

"Dude- Oh..OHH. Too la- *Rolls down window and proceeds to yuck chuck all across the side of the car*"
"NO! MAN! YOU'RE WASHING MY CAR!!!"
