Top definition
The act of drawing a male reproductive organ on the chalk board before class, and then covering it up with a magnet befor the teacher walks in.
The teacher will eventually take notice of the magnet and remove it, resulting in them having a mental breakdown when they see the penile organ.
Works best with strict and/or substitute teachers.
Pranav: "Mark, why the hell are you drawing a dick on the board?"

Mark: "Just trust me."

(Places Magnet and sits down)

Teacher: "Okay class, Today we are gonna learn about the production of rubber in Africa during the late 1890's."

Pranav: "Fuck me, this is gonna be a boring class."

Teacher: "Hey, what's this doing here?"

(Removes Magent)

Teacher: "WHO THE ACTUAL FUCK DREW THIS GOD DAMN PENIS ON MY FUCKING CHALK BOARD!?"

Mark: "You just got the Chalk Cock, Bitch."

Pranav: "Nevermind, This is the best class ever."
