Similar to a Dutch Oven, in which one farts under the bed covers and traps a person underneath said covers, forcing them to sniff your vile ass fumes.

With a Dutch Bun in the Oven, you actually have a length of turd hanging out of your asshole, thereby adding potency and immediacy to the oven.

A Dutch Oven shart.
I almost made my girl puke this morning when I trapped her under the covers and sharted out half a turd, screaming DUTCH BUN IN THE OVEN!!!
