the sexual act of getting head from a lady under a blanket and then proceeding to give her a dutch oven while she is still performing oral sex on you.

Josh: kick ass man! sheila is such a fuckin dumpster slut

When you release a vile, gaseous cloud from your anus in a bathroom, then coax an unsuspecting victim in to said room and then slam the door and hold it shut, thus forcing the inhalation of your putrid flatulence while you laugh
" I was sick of Jerry's shit so i told him that he left his keys in the bathroom, when he went in to check, i whipped the door shut after i took a horrendous loaf and said "Welcome to the gas chamber motha fucka!"

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.

When lying in bed with your spouse, you grab her/him tightly, wrap yourselves completely in the blanket, and rip ass. It causes the fart in the air to become highly concentrated and, since you and your spouse are so close to each other, the temperature rises, further strengthening the fart. Meanwhile, your spouse is unable to move, which forces her/him to smell it. You of course are immune to your own farts.
I don't know what to do. My wife left me because I was gas chambering too often. I miss her so much. I miss her smelling my hot, concentrated farts.

Right before sex (during foreplay) you fart in a condom and stretch it around your partners head (at least to the nose).

Yeah man I caught Baker doing a gas chamber the other night. His room smelled like a Shoney's for weeks.

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.
