killer heartbreak

What you get for doing your best friend's girl or guy. You lose your best friend and usually the girlfriend or boyfriend goes back to him or her because it was a drunken mistake.

I never should have slept with Glenn after the party. He went back to Kate and gave me a killer heartbreak.
