Russian Motorcycle

A sexual act between a man and a partner (male or female). The first step is for the man to lay down on his back, with his hand tied or cuffed behind him. His partner then squats down on his dick, similar to how you sit on a motorcycle. The partner then pinches and twists the man's nipples making him squirm in pain. The goal is for the partner to stay on as long as possible while the man tries to shake them off.

Another classic douche bag move to inflict pain upon your innocent friend. You sneak up behind your friend who is sitting peacefully in his chair. Grab both of his shoulders from behind like you would grip the handlebars on a motorcycle. Then, you make the motion of "revving" your bike, while digging your thumbs into that pressure point right at the base of his neck and make a loud "Vroom Vroom" noise. This move will hurt so bad that the sounds of pain coming out of his mouth will sound like he is speaking Russian.
