Top Definition
In a movie theater, masturbate quietly in your seat. Before climax, cup your hand in the shape of a silencer on the end of your penis and ejaculate onto the back of the head of the person in front of you. Then leave silently out of the theater.

A prank where you wait for someone to go to sleep. Once they are asleep you start to jerk off. Once you are about to cum wake the person up and cum on them. Thus called the "Silent Assassin"
Person 1: "Dude WTF?? Why are you jerking off?"
Person 2: "I'm about to Silent Assassin that bitch in the other room."
Person 1: "OH, HAHAHAHAHA!!!!"
