Brown Slip N Slide

Anal intercourse that involves using fecal matter as a lubrication

Last night, I rode the brown Slip N Slide. It was messy, but man did it feel good.

Brown slide

Is the act of a male going down a slide on his knees fully erect, while a man/woman waits at the end bent over. Upon reaching the bottom the man slams full force into her/his anus achieving the act of balls deep.

I had to take her to the hospital last night to get 5 stitches, after she let me brown slide her.
