A Bloodthirsty Rabid Belieber that will resort to murder if you denounce and insult their deity, Justin Bieber. They also seem to make relentless negative comments to any other well respected normal genre, like metal and rap, since those genres have no correlation to their Goddess, Justin Bieber. A good example of "beliebebitches" is the group that threatened the life of the undercover cop that tackled Bieber. This term can apply to women, and gay men, who adore and worship Justin Bieber. Tread carefully when you anger a Beliebebitch.
