A step above blasting a Dook. Letting loose a Screaming Yeti is a process spanning a period of time, usually an hour. A screaming yeti is a Dook being held in for so long it starts raging in the intestinal tract resulting in a constant supply of rank farts. Releasing a Screaming Yeti is a sudden, and usually painful, experience. It is assumed the smell is as horrid as a yeti itself. Sometimes gutteral vocal assistance is required to force it out.
Dude, I gotta release a screaming yeti
