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

"Jerry barely made it to the bathroom before he released the German Waterslide."

Cantonese Waterslide

A Cantonese Waterslide is a sex move, where you have sex with a Cantonese transvestite while she is dressed as Meg from Family Guy, just before climax, flip her onto her back and pee in sync with her. Then ejaculate onto the flow of piss, causing the semen to flow down her back like a water slide.

"Hey why were you so late to the party"

"I was giving my girl a Cantonese Waterslide while listening to Nettspend, It was awesome!"

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."

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.
