KARRU.
The word KARRU means a mean girl who is very selfish and uses others for her own benefit in such a way that the other person will never know that he is being used. She can even fake God's swear if needed & always puts the blame of her own mistakes on others. She only thinks about herself without caring for others & their feelings.
