One with an incredibly artificial and loathsome personality who is hated by all. This is an incurable disease. Thinks they are beautiful, but most can see through the inner (and outer) beast. Synonymous with "dick
ex. "OMG did you hear what the beast just said to me?"
"Ugh how rude! She's such a beast"
Beast: aren't I so beautiful today?? whoa what's up with ur hair? JUST KIDDING ahahahahaha!!
Others: wow what a dick.
