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.
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!

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.
