1. Used to describe the PDA style phone of a person who is endlessly using it, constantly on the phone, texting, checking email, etc. This person has essentially become the phone's bitch.
2. Used in reference to a Blackberry that has too much bling, too many stickers or is of an obnixious color. The kind of phone a bitch would have.
1. Okay, seriously, do you think you could unglue your little Biatchberry from your face long enough for us to have a real conversation?
2. Girl: Check out what I did to my phone! It's all sparkly now. Don't you just love it?
Guy or Friend: Yeah, nice Biatchberry!
