1)The dense, humid, potent smell of a woman's ass that permeates the air when fucking her doggy style.

2) A hot, lingering, steamy, potent fart.
1)I picked up a hottie from the club, took her back to my apartment and fucked her doggy style. I could barely finish due to the putrid odor of her anal steam. When I was done the whole room smelled like shit.

2)Awww man... I just walked through someones anal steam, I can almost taste it.
