Yellowstone National Butt Geyser

The insertion of one's penis into an anus (male or female), followed by the expulsion of urine, rather than ejaculate, into the anal cavity.

She's going to know that she got a Yellowstone National Butt Geyser, once she realizes I had asparagus for dinner.

Frank Yellowstone

A person that gives great advice. Usually Frank Yellowstone's are people that have deeper problems then they let on to see, but they don't complain when you rant to them. They are people that are great at parties.

Yellowstone

The art of giving your girl industrial strength laxatives then waiting another thirty minutes and fucking her in the ass, unload your load, then watch the magic being as she shits everywhere like the Yellowstone volcano.

I enjoy a good Yellowstone once in awhile, but its a pain to clean up...
