The Reverse Bel-Air only works once, so make it unforgettable.
Girl: Now this is a story all about how, my life got flipped turned upside down, and I'd like to take a minute, just sit right there, I'll tell you about how I became uncertain about our relationship. I think you just like having a girlfriend, it doesn't matter who. I think we should break up.
Guy: ...wait, seriously?
She broke up with him in reverse bel air style.
