sackstick
Sackstick is the adherence of the scrotum to one's thigh. Sackstick occurs when men are physically active or wearing confining pants. We always see women picking at their drawers when the elastic rides up on their asses, but when you see a guy stop and do a double knee bend, he is rectifying a case of Sackstick.
I had been standing in line in the sun for an hour when I noticed I had a gnarly case of Sackstick. Time to detach!
