Guy #1 "OMG what's Elliott doing with his math book?"
Guy #2 "Eww! he's Mathsterbating!"
Guy #1 "So that's why he's sweating so much! Have fun with your Mathsterbation, Freak!"
Mathsterbation is the act of masturbating when a maths problem or assignment becomes too difficult and/or tedious to complete. It is often practised when the subject has lost all hope in completing his maths and can see no other option.
