A person, usually a male, who enjoys the smell and auditory phenomenon related to the expulsion of methane gas from the anus.
One who immerses oneself under the sheets of a bed to smell or otherwise enjoy the expulsion of methane gas from the bed-mate's anus.
A fart-sniffer.
That old fart snaffler who picked Tommy up hitchiking outside of 29 Palms fed him a dinner of beans, brown bread and green beer before taking him to bed. The sonofabitch spent the entire evening under the sheets, sniffing Tommy's farts and whacking his weenie! He gave Tommy a C-sheet the next morning!
This word is used to define the person who hangs around the bathroom for no particular reason other than to (presumably) sniff farts. Their true motives are unknown so one can only assume they enjoy the aroma of a hand-crafted fart.
What's up with Judy? She's always hanging out in the bathroom, the freaky fart-sniffer.
One who loves the smell of his or her own farts. See "self-love" or "self-promotion". Perhaps the ickiest type is promotion of self via projected selflessness.
Fart sniffer - Did you see Raakhee's Facebook post about how she gives all her three-year-old's birthday and Christmas gifts away? She might as well have said, "Let's talk about how amazing I am." Ugh, what a fart-sniffer.
