Well, technically it isn't a word, but an acronym for 'pussy bitch'. It may pertain to someone who is unwilling to something, or acts in a way that is unappealing. PB can be used in anyway to describe anything, mainly people though. People who are PB's lack in courage, are scared to do new things or scared of people, or just generally suck. No one likes a PB, they're lame and...PB-like. When calling someone a PB it generally encourages them to do something they initially don't want to do :D
Are you crying?... Don't be a little PB!

Timmy, because of the evidence at how often you masturbate, how many nudey mags you have, and the fact that you can't hold a conversation that doesn't have to do with Brazilian waxing, butt play, and/or tits, I have concluded that your have a severe case of PBS.
