It's similar to a Dutch oven, where someone farts and pulls the covers over your head ... Except you inflict it upon yourself.

Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.

A variation of Dutch Oven.

When you fart under the covers (while alone, or missing the other person in the attack) and pull the covers over your own head in a self-Dutch Oven. Not to be confused with a Sacrificial Dutch Oven (sometimes Kamakaze Oven) Where you fart under the covers while cuddling someone and pull the cover over both of your heads to ensure the other person bears the brunt of your Methane attack while sacraficing yourself in the act.

When a females head is in the lap of a males, and the male farts and pulls a blanket over the females head or when a male and a female are in bed, and the male farts and pulls the covers of the females head

A variation of the Dutch oven.
This is when you poop under the covers to keep you warm on a cold wintery night.
