yellowstone 

An enormous Supervolcano which houses an incredibly huge magma chamber deep underground which is several miles across and is just waiting to erupt and blow our sorry arses into the next world. Will most likely happen when some 3 billion people are having a coffee break or having a toilet break.

Joe: The sky is dark, its snowing in the middle of july and my home has collapsed from mountains of volcanic ash crushing my piles of porno mags.

Mike: oh well, Yellowstone has erupted. The end of the world has to start somewhere.

Yellowstone 

The first national park in America. The bison will gore you, the bears will eat you and the park service will treat you like a moron.

Yellowstone is an incredible wonder, an awesome place. I will, however, never go there because of how horribly Xanterra treats their employees.

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.
