facebickery
Facebickery is when two people fight on Facebook like they're the only people who matter. They drag every secret out of the grave and no one wants to see it.
'You said I was a bad friend? I'm posting a photo of you skipping my birthday.'
'Why is my teacher commenting on my post? She's still mad I cheated on the test.'
'They're arguing about who had the bigger crush in 2013.'
