When nearing the end of sexual intercourse, the male inserts his penis into the females mouth and releases his unborn children, at which point the female begins to gargle his seed and then spit it high into the air and let it rain down.

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: "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."

in the act of a threesome when a man lays down and jacks off while two women make out right above his dick. When the time "cums", it will shoot upward and hit both of them while they make out.
Greg: Dude, I had my first threesome last night. It was sick.

Joe: Nice man, I'm proud. How'd you finish?

Greg: Did a fountain of youth.

Joe: Word.
