mud geyser 

A method of protest practiced by "Yippies" of the 60's whereas after a large meal is consumed, preferably Mexican, a large dose of laxative is administerd. After sufficient intestinal brewage has taken place, the activist takes to a public swimming facility, and after inhaling a long deep breath, submerges only to emerge ass first (and ass only) to the surface in a populated area of the said public swimming facility for the sole purpose of spraying a fountain of gut grease skyward. The horror in the aftermath is immesurable.

We were enjoying a wonderful spring day at our local lake when we had to make a rapid evacuation due to a filthy individual demonstrating a "mud geyser."

Mud Geyser 

When a woman sleeps with a black man and shoots the sperm out of her vagina.

"Did you hear that Britney was a mud geyser last night?"
