Derivative from the word "rookie" meaning lacking general skills or experience, and "bear" the most terrifying and overpowering of all mammals. It is understood that individuals labeled as Rookbears are incredibly incapable at anything and pose a major danger to themselves and society. Think of a really really stupid bear.
