Dirty Derr 

A sexual maneuver involving two females and one male. Both females are in the "doggy style" position next to each other. The male, with one hand behind his back and the other hoisting an alcoholic beverage high into the air, then proceeds to alternately penetrate both females in the "poop chute" (anally) "raw dog" (without a condom) with increasing speed.

Adam: Yo, did you hook with those two chicks last night?

Mike: Did I hook with them?? I gave them the Dirty Derr my friend!

Adam: Hell yeah man!! That's EPIC!

Dirty Derry 

A sex position in which a male is pounding a lactating woman's b-hole from behind while simultaneously milking her swollen nipples like a cow. After he finishes in her, he pulls out, only to dump the breast milk back into her gaping b-hole. She then proceeds to let it ooze out while softly moaning, "mooooooo!" This position is exclusive to Derry, NH.

Guy 1: "Did you hear about that incident in Derry, NH involving a bunch of pregnant females?"
Guy 2: "Yeah, I was covered in breast milk after I gave each of them the 'ole Dirty Derry."
