To shoot semen. To cum in excitement. To jizz. Etc.

Derived from the Nintendo game "Splatoon", which is actually about humanoid squid people who shoot each other with paint. Not long after the game was shown off, people quickly began using "splatoon" as a verb, as a synonym for jizz.
I just splatooned in my pants when I heard about that awesome new Nintendo game!
You just got splatooned all over.
