When you fart in an elevator and walk out just as someone enters and the doors close before they have any chance of escape. Much like the dutch oven, it will render your victim helpless and paralyzed.
As she was leaving the building, Sarah gave yet another victim an unexpected gas chamber.

Farting while in an enclosed space, such as an elevator, where you victim(s) cannot escape in a hurry. This forces those that are trapped to breath in the odor until it is possible for them to leave.
Once at 2:00 in the morning at the airport I was stuck on an elevator with a young couple and their single, misbehaving crotchfruit who would not stop bumping into my broken arm. Being already pissed about having to travel internationally without much warning from my boss, I decided to get back at them by turning the elevator into a gas chamber just as I arrived at my floor. With the child's face being about ass-height, I felt quite satisfied after.

Similar to the dutch oven. However, this can also be with oneself. Basically, that moment when you fart in the shower and it smells like hell.
"Dude, I was taking a hot shower last night when , all of a sudden, it was like a gas chamber in there. I almost died.
