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?”

While performing anal sex, you pull your dick out and drop several "just-add-water" foam expanding dinosaur capsules in her asshole. Then reinsert, pee in her butt and wait. Some of the dinosaurs will flow out when you're done. The others will stay in there for a while and give your wife/girlfriend a nice surprise the next time she TRIES to drop a deuce.
My girlfriend gave me anal for my birthday.
I gave her a jurassic waterslide for being a bitch all year.

The act of butt chugging from another person's rectum.
Person "A" first performs a classic butt chug. Next, while maintaining hold of the alcohol of choice inside their rectum and hose still attached, the other end of the hose is inserted into the rectum of person "B". Then person "A" expels the alcohol through the hose and into the rectum of person "B" thus completing the Devil's Waterslide.
