I'm Gonna Cum On You - A loud and proud way to say you're about to lose your mind,

A loud and proud way to say you're about to lose your mind, usually because you're too high, too tired, or just too happy.

I'm gonna cum on you, I just finished my 10th video game.

I'm gonna cum on you, I just got a new pet turtle.

I'm gonna cum on you, I just ate a whole cake.
