backstabbing ingrate
Friendly, accommodating and often outwardly pleasant however harbors a deep resentment towards the ways of the world. You cannot give empathy to or trust a backstabbing ingrate. Everything you share will be repeated to others and used against you in one way or another. A backstabbing ingrate will always return to what they know best; often a white trash upbringing surrounded by alcoholism and family disfunction. When you feel the sting of betrayal you know you have met a backstabbing ingrate.
I am not interested in what she does anymore and don't care what happens to her. She is poor white trash and a backstabbing ingrate, and always will be.
