Waterslide surprise

When a male is travelling down a water slide and somehow the genitalia suddenly reverse direction and become crushed under the body. The genitalia then proceed to experience extreme friction for the rest of the ride. This is somewhat surprising.

Ricardo was travelling down the slide and suddenly he had an expression of anguish because of waterslide surprise

Vienna Waterslide

Receiving oral sex by two women located on either side of the penis. Particularly length-wise tonguing of the shaft, simulating a sausage on a waterslide. Coincidentally, (Vienna,) Austria being the location where one has a very high probability of receiving oral sex.

Derek: I rode the Vienna Waterslide last night.
Charlie: That sounds fun, I've never been to a water park.

The Waterslide

When you feel a shit coming out that's so incredibly massive, you flush right before it's about to hit the water so it doesn't fold and clog the toilet. The shit, rather than come to a rest in the toilet bowl, then rides the pipe-waves down to the sewers.

Hey guys, sorry I clogged your toilet. I forgot to turn on the waterslide.
