throttle dog

(1) bowel muscle, or muscle that alows one to shit. (2) muscle that women must relax to enable anal sex.

example:
Mitch- "i fucked her in the ass, and then she had to jump in the bath tub because she started bleading"
Wess- "why was she bleeding?"
Mitch- "i knocked her throttle dog loose!"

1. Gear-banging, full throttle, red-lining, tire squealing, WOT, checker flagged chick with a wrench FTW. A babe who spends more time perfecting her ride than she does her hair and is turned on by the smell of gasoline and exhaust.

Dude #1 ~ OMG! Did you see that F-I-N-E, fine throttlehog in the GT 350 fly by us like we were sitting still?!
Dude #2 ~ Are you kidding?! All I caught was a flash and the sweet sound of an exhaust at WOT!
Dude #1 ~Damn!
Dude #2 ~ Damn!
