FOMO 

(Acronym) Fear of Missing Out

Used when you've either been invited somewhere and can't attend for one reason or another. Or, when you haven't been invited somewhere and everyone else is going.

Kate: "Have you been invited to the hottest party of the year next week that everyone is going to?"

me: "What invite? No, I'm not. Is everyone going to be there? I've got serious FOMO"
