A BitchWeezy is someone who's hella chill such as your friends or someone who is REALLY getting on your nerves. If your friend calls you bitchweezy then you shouldn't be offended , but if some person you don't even KNOW calls you it then you must be getting on their nerves. So basically its a compliment if your friends call you it. It's like saying hey niggaaa! to friends but to strange people then that could be an insult.
Good Bitchweezy - Hey Bitchweezy! Hey Bitchweezy! wats up? Bad bitchweezy - Wow. Umm your really being a bitchweezy. Its kinda annoying.
