German Waterslide

When you have uncontrolable diarrhea and a massive shit log comes in strong off the port bow and fires out of the cannon at uncontrolable speeds followed by another 10 second blast of diarrhea causing a hiroshima sized splash back

Jurassic waterslide

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.

Devil's Waterslide

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.

Daniel and Tommy say their gonna do a Devil's Waterslide at the party tonight.
