Waterslide 

When you and you're partner are amidst "doggie style" sex; right before you cum you pull out and push your partners head and shoulders off the bed onto the floor. Your partners back now is sloped from the bed to the floor. You splooge on your partners back and decide to ride it down like a waterslide.

Mark - Damn Lisa why do you have a bruise on your forehead

Lisa - Me and my boyfriend were having sex and he waterslided me! And my back hurts too.

Waterslide surprise 

When a male is travelling down a water slide and somehow the genitalia suddenly reverse direction and become crushed under the body. The genitalia then proceed to experience extreme friction for the rest of the ride. This is somewhat surprising.

Ricardo was travelling down the slide and suddenly he had an expression of anguish because of waterslide surprise

Waterslide Enema 

When you go down an steep waterslide and the water is forced up your butthole and gives you an unwanted enema.

When at the waterpark I like to watch the women at the end of the steep slide, they pull their bathing suit bottom from the crack of their ass and then you see water run out of their ass. “Did you see her waterslide enema flow out of her?”
