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.
A person(s) who purchase a 90k campervan, RV or caravan and sit inside all day and all night inhaling each other’s farts. They do not mingle or crack a smile at other campers because they’re too intoxicated by their own farts
Look at those snobby grey nomads, probably sitting in their camper being a bunch of fart sniffers
A person who's so damn lazy and slothful that he's developed chronic constipation. As a result the highlight of his day is enjoying the copious amount of farts he produces as a consequence!
Good Lord! Ever since that Fart Sniffer's been out of work, he just sits there in front of his computer letting one rip after another! Frankly I'm afraid to enter the room without a GAS MASK!
A Fart Sniffer is another name for a Bathroom Exhaust Vent or Bathroom Exhaust Fan. You know, the fan in the ceiling of the bathroom that you turn on with the wall switch after stinking upthe bathroom when you poop.
