FOMO

FOMO stays for "fear of missing out."

Oxford Dictionary defines FOMO as "Anxiety that an exciting or interesting event may currently be happening elsewhere, often aroused by posts seen on social media."

The term was coined in 2004 by Patrick J. McGinnis, an author who referred to FOMO and another related condition, FOBO (Fear of a Better Option) in an op-ed titled "McGinnis' Two FO's: Social Theory at HBS" published in The Harbus, the magazine of Harvard Business School.
