While screwing a girl doggy style (traditionally through the Tradesman's Entrance, but vaginal penetration can be an unofficial variation), the male takes hold of the girl's hair (like a horse's mane, or saddle reins) and proceeds to shout out the name of the girl's sister (or best friend) in mid-thrust. The male then grips the hair even tighter and sees if he can hold onto the subsequent bull ride for 8 seconds.
While Randy was banging the crap out of Sonya from behind, he shouted out Sonya's sister's name, Claudine, in mid-thrust. Sonya fell into a blind rage, thrashing about the bed like a wild bull, and Randy held on for dear life, like a Turkish Rodeo rider.
