The pasty, smelly, and gooey substance that is found in the grotch area all around the ball sack, taint, and inbetween the legs. It is fermented from sweat, anus juice, dead skin, and cotton lint from the underwear or jock strap. The color of the Fromunda cheese is usually dependent upon the color of the underwear being worn at the time. Although the anus juice can have an effect on the color also. The smell is dependent upon the frequency of showering and length of time in the fermentation process. The taste is similar to the way it smells.
Q: Where did you get that really smelly, stinky, pasty cheese?
A: (pointing down his pants) Down From Unda! Fromunda Cheese!
