look up any word, like yeet:
 
1.
The thin layer of smelly, sweaty film that accumulates on a man's testicles after a hard workout. Typically one can smell skime through their shorts several hours after the workout if they do not shower. Caution: Skime is gooey and slippery to the touch and a smelly residue will linger on your hand immediatly after testicular contact.
