Chattanooga waterslide

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.

I heard that carl accidently gave lacy a chattanooga waterslide. Wow carl is such a tease!

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.
