Faux Mo

Fear of missing out on imagined fun you think everyone else is having.

Dave: I never get invited out to anything anymore.
Lauren: Like what?
Dave: You know, parties and stuff. Down the pub or nights out.
Lauren: Mate, you have a serious case of the faux mo. I'm not sure what you think we're all doing, but I can assure you I spend most of my weekends falling asleep in front of the TV with a bottle of wine, only to wake up and find the dog licking my toes.
