(This works best while the male has some sort of explosive diarrhea) A man lies on his back with his legs wide open while a woman slowly progresses (face first, mouth open) towards his testicles. Once the woman is approximately 3 inches from the "ball-sac" the man then releases massive amounts (or whatever's in his system) of diarrhea on her face, with the intentions of shitting in her mouth. Whether the crap landed in her mouth or not doesn't matter. A successful "Mouse Trap" has been executed.
Christy was trying to suck my balls before landed in a "Mouse Trap"
When a guy is getting head, he says somthing like "Oh S*** what's that?" and points, when the giver turns to look, they tuck the penis between there legs. When the giver returns to finish the job, you spread your legs, having the penis hit the giver in the bottom of the jaw.
A mouse trap is the pro-female version of the donkey punch. While the female is on her back the male is standing and penetrating. When the female nears orgasm she punches the male in the eye causing him to pull his upper body back and yell "WTF bitch!", but also causing him to thrust his pelvis forward for maximum penetration. A donkey punch and mouse trap may be possible simultaneously, but is purely theoretical at this point.
"How'd I get this sweet black eye?", you say. Well Kelly caught me in the mouse trap last night.
