A chili dawg is not when you shit between a girls butt cheeks. A chili dawg is when you shit on her chest between the females breasts. You than use your dick as the hot dog, the shit as the chili, and her tits as the buns. The bigger the buns the better i believe.
Girl: What do you want to do now?
Guy: I am going to give you a chili dog, lay down and take off your shirt.
Girl: Chili Dog?
Guy: Shut up (man than proceeds to shit on chest and thrust in a largesse manner.)
