When a mans giant pecker is overused, it creates a substance other than semen called sweat. This sweat can cover the poor males testicles causing an extreme case of Sweaty Ball Bag.
Sweaty ball syndrome or SBS is what happens when you get done with a workout and your balls are just dripping sweat, it also happens when you play sports or sleep.
Me: Dude! After that workout I have some severe Sweaty ball syndrome!
Friend: You mean SBS?
Hey babe, after sleeping last night I have some major SBS.
