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!"
