pube noob

An adolescent boy who is just getting his first signs of "hair down there", and thus acts like an obnoxious adult.

Guy 1: "Dude, he got so carried away trying to prove he was stronger than all of us that he sprained his freaking back."
Guy 2: "I know, huh. He totally acted like a pube noob."

Older brother: "God, my little brother thinks he's all hot shit since he's going through puberty."
Friend: "Looks like you've got a pube noob on your hands, bro."
