First of all, I don't advise anyone to try this. A czechoslovakian wardog occurs when two guys stuff a girl in the ass at the same time. She then takes a shit with a widened asshole that comes out the shape of a cookie. The gentlemen then proceed to rub the girl's face in the feces, hold her head to an oven until the shit dries, then have her scratch it off her face.
- Dude, me and Mark gave Tina a czechoslovakian wardog the other night
- That's revolting, you scumbag
