facebickery
Facebickery is when you and your dumb friend argue on Facebook like you're both the last people left. They post every single stupid thing they ever did and no one wants to see it.
'You said I was a lousy friend? I'm posting a photo of you at my birthday party with your ex.'
'Why is my sister commenting on my post? She's still mad about my failed relationship.'
'They're fighting about who had the better crush in middle school.'
