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.

Get the Jurassic waterslide mug.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."

Get the Washington Waterslide mug.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.

Get the Australian Waterslide mug.When you are having sex and the penis slips out of the vagina while on the "backstroke" and you thrust forward and the penis forcefully enters the anus.
