Mad Scientist
A guy who shoves a glass tube up his partner’s butt and then jizzes into it like it’s a science experiment, then hits them so hard it breaks the tube and everything inside comes out like a messed-up lab explosion.
I tried mad scientist on my roommate, and now he smells like sperm and shattered glass.
My boyfriend did the mad scientist thing and I got glass shards in my poop.
My mom said I was a mad scientist because I used a Pyrex cup for my first time.
