An annoying kid in high school, usually a freshman, that still hasn't hit puberty yet. Characteristics include a light voice, no girlfriend, a lot of hair (on the head I mean), and a very immature personality.
If this prepube doesn't get away from me, he's gonna have a bunch of fist marks on his face.
A child, younger than a teenager, usually female but can be male. Derogatory.
Oh, no! It's only 6:00 AM and already there's a prepube going to school on this bus! Now I have to stand and hear her screaming for a whole hour!
