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.

Australian Waterslide

When a male ejaculates into the center of his partners back and has it slide down their partners back, down the butt-crack where it is then slurped up by yourself or a third person.

Dude you should have seen it Chad had Jason give his girl an Australian Waterslide at the Party last night.

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?”

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.

Washington Waterslide

The act of filling a waterslide with piss and cum and diving head first into it. It is fully enjoyed when you do it with multiple people and have sex in it afterwards.

"Did you hear about Jame's Washington Waterslide at his house last Friday? everyone contributed to fill it up!"
"Wow talk about a group effort!"
"I wish I went but I was too busy enjoying my girlfriend's Mississippi Birdbath."
