Masturbation Forearms 

Masturbation forearms are caused by excessive masturbation. They can be identified under two conditions:
1)When one's forearms are disproportionate to eachother
2)When one's forearms are disproportionate to their upper arms (Think Popeye)

"Dude, I think you've got muscular forearm syndrome"
"What makes you say that?"
"You have masturbation forearms! You're right arm is bigger than your left!"
"...shit"
