When one masturbates with their left hand because everyone else masturbates with their right.
"Everyone shakes with their right hand, so you can't let your right be soft! That's why I masturbate with my left hand."

"Wait, so you masturbate with your left hand because no one else does?"

"Yeah"

"Hipsterbation, bro. Stoppit."
