Belgian Waterslide
When a male is receiving oral sex, and the male tries to get a Chili Dog (when he comes, he pulls the girls* head so hard his cum comes out of her/his nose) a belgian waterslide is in fact a Chili Dog gone bad, at the same point the guy pulls , the other person throws up covering everything in puke, rather then sperm
When Shaft tried to give the hoe a Chili Dog, she choked and pulled a belgian waterslide on him, covering his nuts in vomit..
