Where you jerk off under someone's bed to scare them. Upon finishing, you shout "HAPPY HALLOWEEN" in your scariest voice.
"Hey, Jimmy, what did you get up to for Halloween. Costume party?"
"No, I just went on a monsterbation spree. Scared the little bastards senseless. It was both a trick and a treat."
"This friendship is over."

The act of playing with one's monster unit in an app game in the restroom. At times, it is also done in public. It is a very vulgar act. Stroking, fingering, touching, and aiming are various ways in which one can play with their monster. At times, one can monsterbate furiously and come out not knowing how much time has passed.
Bob: Jim is taking an awful long time in the restroom.
Joe: He's probably just monsterbating in there.
To be caught in the act is to bring shame to oneself.
Jared: G..Gina! What are you doing here? I thought you left!
Gina: I forgot my keys. Wait, Jared? Oh my god! Are you monsterbating in public? Ew. That's just gross.
