When you have not gone to the bathroom in a few days and really have to go and as soon as you pull down your pants your shit comes out and splatters everywhere like a geyser.
(in a public bathroom) "Woah, why is there shit all over the walls?"
"The guy who just walked out had the biggest ass geyser I've ever seen"
