A very chilidish act performed when someone is in the restroom and turns on all the sinks then runs away thinking if he stayed he would get in trouble.
(Freshman turns on all sinks then runs)
Freshman: "HAHAHAHAHAHAHAHAHAHA!!!!!!! I'm going to get away with it."
Senior 1: "Wow, what an idiot. He thinks he's cool.
Senior 2: "I know, I stopped thinking the Fountain of Youth gag stopped being funny in 7th grade."
