musty nuts 

Balls that are unclean, sweaty, and hairy. Balls thats have a rank stench.

After I was done playing softball with the boys I had a bad case of musty nuts!

Musty Nuts

The piquant aroma that blooms in the crotch when one sweats profusely without showering for multiple days in a row.

*Fresh stank is not yet sufficient to earn the label "musty" as the funk must percolate for a minimum of 48 hours to achieve the properly aged stank of Musty Nuts.

I worked out four times this week and haven't showered once! I bet I got some serious musty nuts goin on

Mushy Nuts

A form of torture involving very saggy nuts. A person is suspended in a form that lets their "shit" hang for another person to punch very hard. It hurts very bad.

Dude my Mushy Nuts hurt really bad last night.

mustynuts 

A scrotum that is infrequently washed and has a resultant pungent, moldy or mildewy odor similar to a semi-clean but oft-used public toilet.

I was gonna blow him until I got south of the border and got a whiff of his mustynuts.
