Splash Mountain

Splash Mountain:
When you are fucking someone doggy style, pull out, and nut down their butt crack starting from the top.
Right as the nut reaches their booty hole you put your face next to their ass and clap their cheeks together causing a cum explosion similar to that of the ride "Splash Mountain" at the theme park known as "Disneyland".

"Bro Jessica let me go to Splash Mountain last night it was my first time. She even setup the camera for a picture just like the ride at Disneyland. Wanna see it?"
