Facebounding
You're too angry to be sad, so you post all over Facebook about how you're fine, and how your ex is the worst. You lie about your new life, and you make fun of them in the comments.
My ex is still single? They're lucky I'm not posting a photo of them crying in the park.
I got a new job. My ex is still stuck in their sad little life.
My ex asked me out again. I laughed so hard I cried.
