Get the Crusty dusty mustymug. by Froggyboy74 May 8, 2021
Get the Mustymug. Happens most likely when you're sleeping on a couch and a cat sits in your lap and warms up your crouch. Thus later on when you wake up your cock'n balls are immersed in sweat and have been incubating the foulest bacteria.
I passed out on your couch and your cat gave me Musty Jacobs disease!
I gotta take a shower man, i woke up with some serious musty jacobs disease!
Watch out for that cat its gonna give you musty jacobs disease.
Man i can smell your f**n musty jacobs from hear.
She wasn't stoked on the bad case of musty jacobs disease i had.
Had to burn my boxers. Damn cat gave me musty jacobs disease.

Get the Musty Jacobs Diseasemug. A long, drawn-out, disgustingly sweaty, borderline unhygienic sexual encounter that feels more like a test of endurance than an act of passion. Usually involves excessive body odor, questionable lubrication, and an overpowering musk that lingers in the sheets for days. Often results in deep regret, dehydration, and the need for multiple showers.
"I thought we were gonna have a hot night, but it turned into a full-on musty slog. I had to burn my sheets afterward."
