The greasy, sometimes salty mixture of sweat, dead skin, hair, died urine or smegma, dingleberries, and motor oil that accumulates under the clothing of someone who hasn't showered in several weeks. The color varies from pale yellow to a yellowish-brown and had an odor reminiscent of deep fryer grease, gasoline, and taco seasoning.

Not to be confused with curmudgeon.
"Dude, will you please take a fucking bath? I can smell your scurmudgeon from like 20 feet away."

"I'm not letting you ride in my truck until you wash all that scurmudgeon off your fat ass."
