When a person farts in the shower, and the steam from the shower holds the fart in, thereby surrounding you with your own fart. Dutch oven meets steam shower.
When you are ramming a dude with your ass and your ass isn't so fresh and what you really need is a jizenema, you say, "Clean me, Victor." As the guy jizzes, you leak chocolate man milk. Thus, your oven is cleaned.
I had the trots real bad last week, but Rodney gave me a dose of the self-cleaning oven last night. I am gonna save a bundle on my colonics this month.
when a criminal becomes the victim of a crime because he victimized someone at an earlier time; in other words, karma comes back on the criminal, the problem takes care of itself without the need for police or legal intervention. In theory, eventually all crime should diminish because of this theory, the oven should clean itself.
"Man, that banger got shot because he jacked those same dudes last week...it's okay because now his crew will roll back on them...they don't want to make a police report, it's a self-cleaning oven."
