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"
Billy's fomo grew stronger when all of his friends had tickets to the upcoming show! Against all good reasoning he went to the venue anyways without tickets!
Short form for ‘fear of missing out’. The feeling when you see a huge green dildo on a chart and you don’t own that coin, so you sell other shit to buy into it freaking out. As crypto trading is still very much driven by emotions rather than valuation, FOMO is a huge factor to consider when swing trading in crypto.
