FUMS

Fucked Up Mouth Syndrome

Someone who has an unattractive mouth or teeth, but is otherwise generally attractive. A butter-mouth.

Generally referred to when talking about a mouth that has not been seen yet, usually due to mask wearing.

John: “This new girl at work is so cute, I wanna ask her out.”
Bill: “Have you seen her without a mask yet? Watch out, bro, she could have FUMS.”

———————

Dave: “I matched with this girl on Tinder, but she has no pics of her smiling at all.”
Jim: “She probably got massive FUMS, man. Unmatch for sure.”

Fum

When you fart on a soft cloth seat and the cushion takes on the smell.
Fum can last for days releasing itself slowly as the gas expells overtime - or - Fum can release in a quick poof upon a heavy seating.

Damn. Did you just fum the couch?

Brynn laid a nasty fum in my mattress last week. It still gives off a whiff whenever I hop into bed.
