it's what you can do to someone on a hot afternoon when your testicles are drooping extremely far down...it's a 2 part process...you take a sweaty ball in the palm of your hand, and the other nut in the other hand and stretch them out as far apart as possible, this is easy part...for the 2nd (and more difficult) part you you gotta find a slutty bitch who's down for the clown, and you get her in any of many sexy submissive poses and stretch your nutsack over her face...if you do this correctly you should be able to get both balls all the way around to her ears...its quite a sight because you can see the imprint of their face poking out through your scrotum

When you sweat intensly, specifically near the groin, and your ball sack sticks to your leg. You Try to move your legs, or shake em, to try to destick them balls from your leg. Its very annoying, because you try to unstick them, and it doesnt work very often, unless you use your hands. It would be quite rude, if you were seen in public.
Man that soccer game was intense, the gym was sooo hot, and man, my shirt is drenched, ive got a bad case of ass sweat, and ive got a batwing. How pleasant.
