I need some Last words?

My former best friend is leaving this summer, and tomorrow's the last day I'll ever see her as we're finishing school. She's not my friend anymore because she stole my boyfriend (I hate him too), and has been absolutely horrible to me these past weeks. I want some memorable parting words, like "you were my best friend but you betrayed my trust because you're a complete ***** and please **** off", but more poetic. I know it's mean but I want her to be hurt, so she knows what it's like. Don't give me sentimental crap about forgive and forget because that's not happening. I just need some good parting words. Thanks ^^
