Reverse Slip-n-Slide 

When one man (or woman) gets on their hands and knees and inserts a funnel into their butthole as another pours milk down the tube into their ass. After this point the milk chugger will have to shit and diarrhea will fly out of the funnel backwards creating a reverse slip-n-slide.

The other night I did a reverse slip-n-slide at my girl's sweet 16...shit was wild

Reverse Slip n Slide

When a man pumps a slip n slide with lube instead of water and a woman sits at the opposite end of the slip n slide with her legs open. The man then runs, jumps onto the slip n slide, and tries to do the coolest pose he can as he slides down the slip n slide. He slides all the way to the end, using his speed and force to penetrate the woman at the end.

Brad: Justin, why are you so oily?
Justin: Me and my girlfriend did a reverse slip n slide. I did a handstand all the way down and slipped right inside!
