thunk

Derived from the sound food makes when falling from a row in a vending machine, "thunk" is a general term for food you buy when you have the munchies, but your funds are limited to small change only.

Imagine the sound made by a Honeybun when you buy it from a machine after smoking pot all night.

Dude, you're eating thunk.

Dude, let's go get some thunk.
