someone who doesn't wear underwear.
I consider myself a freeballer because I hate underwear.
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!"
the act of not wearing underpants (guy specific) which lets the men roam free
Cuz im free
Freeballing
The act of doing something without thinking.
Sarah: "You guys have a monologue due next week, so you should start that soon."
Loucas: "I don't have to start it! I'll just freeball it."
When a guy doesn't wear any boxers OR briefs underneath his pants, he is pulling a "freeball". The balls are free!
"Dude, you can't freeball when you have wigger jeans on.."
