Asschmech 

Similar to Ballschmech, Asschmech is the build up of a slimy like substance made up of ass sweat, toilet paper, feces, and anal leakage, cultivated after only a week without showering.

JoBryan: man, what's up with your ass? It's so slimy!
Jumpy Jim: huh? Oh, that's my asschmech. I really need a shower!
