Going without undershorts, said of a male, so called because his balls hang free and unencumbered. A similar expression is "going commando," which can be used of either a male or female without underwear, but is more often used of a male.
"A lot of guys like to freeball in the summer, but I prefer jockey shorts, to give my balls a little support, since otherwise they hang too low in the heat. I do freeball if I'm anticipating a sexual encounter, however!"

When a guy doesn't wear any boxers OR briefs underneath his pants, he is pulling a "freeball". The balls are free!

1. When you freeball a chick, you run the chance of getting an STD.
2. I freeballed my girlfriend last month, and now we think she's pregnant.
3. I can't believe he was freeballin' that girl! Who knows what he could have caught?!

Exhibitionists practice within some groups wherein one does not wear underwear in conjunction with thin fabric or very short short shorts, allowing ones penis and testicles to be viewed by others as they sit or walk about. Provides cheap thrills for both the exhibitionist and voyeur.
