FU

Short for Fecal Urgency. Severe diarrhea that comes on so fast that a bathroom must be found within a matter of minutes because it's coming out no matter what. Often contains little or no solid matter and feels like you're peeing out your ass. Frequently occurs the day after a long night of drinking

Those Jager shots I did last night caught up with me around noon and I had to stop at a gas station for a major F.U. attack.
