A condition caused by excessive lint (commonly present in a new pair of underwear) clinging to the scrotum after the first use. The fuzz will fuse with ball sweat or Fermunda Cheese giving the appearance of an African-American's scrotum.

An excretion of a sweaty thick substance from the sack area that smells sour. It can be found by twiddling your index and middle finger on your sack after not showering for days.
I had so much sack oil I could have swabbed the ball deck and made a candle. So much scrotum scum oil.
