when you see a friend request from someone you know but who gave you the worst side-eye ever, and you let it sit there like a rotten egg in a lunch bag for weeks before you finally accept it just to rub their nose in it
My ex from middle school sent me a friend request. I left it for two weeks just to annoy her.
My cousin texted me 'Why haven't you accepted my friend request? I'm still mad about that time you ate my pizza.'
My old rival from soccer left a friend request. I let it linger for a month because I'm a petty god.
