starting off with simple tea-bagging, making sure that her nose is between your ass cheeks, and as she is jacking you off, you fart as much as possible.
I know she wants a dirty gas pump when she insists on paying at the local mexican restaraunt.

While pumping gas, you try to release the pump trigger at the number you want it to land on in one try. The less risky people release a few cents underneath the target number then pump the trigger until it gets to the number. It is kind of reverse of russian roulette.
Pumping gas this morning, I tried to land on 30 dollars exactly but hit $30.05 instead. I lost gas pump roulette today.

A sexual act used as a finishing move. Mimics the activities of an Oregonian gas station. 3 people are required for this act: one is the Recipient, one is a Bum, and the third is the Pump. The Bum swipes the Recipient's credit card in the Pump's ass crack. This allows the Pump to release their fluids into the Recipient's throat. Optional: the Bum yells "FINISH HIM" as the Pump is about to release their fluids.

(An alternative of the Washington Gas Pump)
"Hey Jerry, you should get Tom to come over so that we can do the Oregon Gas Pump properly tonight!"

"Honey, I can give you the Oregon Gas Pump, but we will need to find somebody extremely unemployable to swipe my credit card."

"Hey Bobby, want to play Mortal Kombat X while Tina and her Bum friend perform the Oregon Gas Pump on us?"

"These Oregon Gas Pumps are more satisfying than a bukkake in Africa."

The Austrian gas pump is when You feed your girl large quantities of food, and she is so full of food that she needs to shit a lot. Then you fuck her in the ass and the shit explodes causing it to go all over you shirt, pants, and dick.

Adding a little southern twist to the traditional British tea bag, the woman brings the man's testicles into her mouth while facing his backside. As she performs a handjob while "tea-bagging" him, the man should flatulate as much as possible. With her face buried deep in his behind, the man's wind will provide an odorous addition for the woman.

From: "Dirty Sanchez's Guide to Buck Nasty Sex"
I think the key to surviving a Dirty Gas Pump is breath control. Eventually you learn when to breathe through the nose, alternating with removing the balls, for deep breaths through the mouth. It's not hard, but until you get the hang of it, it's not pleasant.
