When you go on a social media dig and unearth old posts just to annoy someone by bringing up their old, embarrassing, or stupid stuff.
Liking a 2018 post about how 'avocados are the future' when the person is now 30 and works at a gas station.
Commenting on a 2015 status that says 'I’m gonna be rich by next year' while they’re still broke.
Tagging someone in a 2013 photo of them wearing a hat that looks like a toilet seat.
