The day you become a man, the cock vicegrip rule is when a girl or woman takes the right elbow and puts your dick in the inner of her left elbow and then elbows with her right elbow onto the left elbow where your cock is. Only real men do it don't be a pussy.
When a man is grinding his boner into his girls butt cheeks and she clenches and squeezes your nut sack into her crack and pulls away and you cant break free.
Last night, my wifegave me an Iowa Vicegrip. Now, my nuts are super sore.
Zappa:"She had my balls in a vice but she left the dick, I guess it's still hooked on but now it shoots too quick. Oh god I am the american dream, but now I smell like Vaseline and I'm a miserable son of a bitch, am I a boy or a lady, I don't know which."
