"floating under the influence"; floating on a tube or raft down a body of water, prefferably a fast moving river, while shitcanned (i.e. wasted or fucked-up on any drugs)
Yesterday, while tubing down the mighty Mississippi, Jimmy got a FUI for being intoxcated while flashing his "down-stairs mixup" to the police; his wasted ass went to jail.

Fucked up individual. Usually someone who has done something that is viewed as socially or morally wrong.
Did you hear about Eric beating the hell out of Cam last night? He's in the hospital and he might never recover! Damn, what an FUI.
The old gym teacher got caught with illegal pornography on his computer. I always knew he was an FUI.
