A device for smoking marijuana. Normally used when nothing else can be found (ie. papers, a bowl, bong, etc) Fuckits usually consist of tinfoil and/or a plastic bottle.

-Name given when everyone is too fed up with searching for a smoking device.

"Ah fuckit, get the 2-liter. We're making a bowl."

"Screw finding the bowl man, just grab the fuckit."
