It is where a girl (Preferable with a Vagina) is riding yo dick and then twists around in a 359 degree motion and then pushes her stomach forward bending your dick and snapping your dick with the possibility of ripping it off.
Person 1: Yo, my girl just did the Double Reverse Dick Bender Person 2: Damn, did it hurt
Person 1: Yes, my dick is permanently sticking up now
Person 2: Remember to remind me to do this next time I get a chick at the bar
"Man, Maria, you hoochy mamma!!....you're such a dick bender. You sprained my dick for the 5th time this week. You keep this up, and I'll be able to pee around corners."
When you are having sexual relations with a big ol' Girl and she is on top and your penis slides out and her big ol' Booty slams down on your harddick bending it in ways a mans penis should not bend.
Me - Hey dude I was getting rode by big ol' Darlene last night and she bent my unit in half.
