It's when two people argue on Facebook like they're the last two people on Earth. They spam the comments with their drama and everyone else gets stuck reading it.
'You said I cheated on you? I'm posting a screenshot of your DMs with your new guy.'
'Why is my mom commenting on my post? She's still mad about my failed relationship.'
'They're arguing about who got the last cookie in the lunchroom in 2009.'
