When you sneak a peek at a Facebook chat between two people who don't care about you and feel like you just got publicly shamed.
I face-dropped when I saw my ex and his new girlfriend chatting about me like I wasn't there.
She face-dropped when she saw her crush and his crush talking about how annoying they both are.
He face-dropped when he read about his mom and her coworker planning a surprise party for him.
