1. A foul smelling foreskin.

2. Dead skin that collects between the toes, under the arm, inside the elbow, etc. This skin is a sage color and smells disgustingly.
1. Nathan: (Pulls back his foreskin) Dude! Check out my knob!

Mikey: Eww! Man! That shit stinks! You got something nasty growing under that funkskin of yours...

2. Katelyn: Get your feet off of me, Robbie!

Robbie: Why? I thought you had a foot fetish?

Katelyn: Well, not when you got nasty, rotting funkskin on your feet, cheese toes!
