Slimy Slap 

The act of masturbating into one's own hand then slapping someone with a hand full of ejaculate.

Person 1: What the fuck was that?!? Someone just ran by and slapped me in the face!

Person 2: Oh man, you totally have cum in your ear. I think you just got slimy slapped.

when you finish having sex and you take the condom off, run upstairs and slap your brother in the face with it while he's sleeping.

Brother: last night.. i think something hit me in the face while i was sleeping, but i dont know i didn't wake up.
You: did it feel like a slimy fish slap?
Brother: Yeah, i think so!

Siberian slime slap 

The act of ejaculating in one’s hand, then proceeding to chase another person with the goal of slapping them with a handful of nut.

My friends always run away in fear when I try to attack them with the Siberian Slime Slap
