facepost regret
When you post something on your friend's wall to be mean, but then you panic and delete it, not realizing they already took a screenshot and are laughing at you in the bathroom.
I posted 'You’re a joke' and then deleted it. She showed me the screenshot in the bathroom. I cried.
He posted 'You’re fat' and then ran. She posted it on Instagram. I died.
She wrote 'You’re a loser' and then erased it. He took a photo and sent it to everyone. I got 12 DMs.
