"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.
