Masturbating Monkey

When a monkey in the forest or at the zoo get's a erection and grabs his penis and starts to jack off like a car piston and starts shooting sperm all over the place, then he goes "HOOO OHHH AAAAAAAAAAAAAHHHHH HOO HO HOO!!!!" when the male monkey starts to think oh the female monkeys. and sperm starts to land on you and you child.

Child: mommy, WTF IS THAT BLACK MONKEY DOING?!?
Mom: Don't be racist!!! He's just a masturbating monkey

Doctor: hey Steve, that monkey seems to be masturbating?
Steve: I think he is, we should test his heart rate to make sure it's safe for the masturbating monkey.
Steve: ok... WHAT?! IT'S OVER 9000!!!!!!

masturhating

The equivalent of a cock block, but when it happens during solo masturbation. Someone knocking on the door while a man is jacking off inside would be masturhating.

Jon: So what'd you do yesterday man?
Alex: I was bored as shit so I was just jacking off until my brother knocked on the door. Totally masturhating.
