Pulling your cock out of female when doing her doggy style, then placing the cock by the rectum and rattling it back and forth between the ass cheeks to see if she is interested in some anal.
I was nailing Kristen last night, and in the midst of our session I did some Rectum Rattling. As usual, I was denied.
To vent your frustration; either loudly or through the Internet. Most people prefer the Internet, like going to VentNation.com or related sites, or going bat s--t crazy and ranting in someone's face. Sports fans and TV personalities enjoy ranting the most, and so do girls amongst their friends.
Person 1: Why are you ranting?
Person 2: Because I'm unemployed. I don't have a girl. I hate my life! FML!
Person 1: I HATE THE PATRIOTS. TOM BRADY IS A NO GOOD PRETTY BOY AND BELICHICK IS A BELICHEAT.
Person 2: Stop ranting and calm down!
