Chili dog slam
The act of a taking one's penis (hot doggy), laying it in between a pair of butt cheeks longways. Then the receiver squirts some nasty poop on the hot doggy, while getting their cheeks slammed together, creating fountains of glorious chili flying everywhere.
Hey Jake, I'm really wanting a hot steamy chili dog slam right now, my buns are aching to be slammed.
