The act of eating spicy Mexican food, waiting a duration and then defecating on your partner’s breast followed by sexual intercourse with said breast. If done correctly, the surface will be quite slippery and also spicy enough to burn your pee hole.
After eating Mexican Food, Johnny and Carla were feeling frisky. Carla asked Johnny to give her a Mexican Slip N' Slide . So he shit on her tits and fucked them. The burn in his pee hole didn’t stop him from finishing.

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!
