Once again, Ego is here to expand your Ivy League vocabulary. After a weekend of late night halloween party–hopping and enough Facebook uploads to to make you scream, we’ve got just the term.

FOMO (noun) [pronounced fo–moe]

A term referring to the tearjerking emotion that comes with the fear of not being included in a specific night, event or photo. Expanded to Fear Of Missing Out, this acronym is most often used in reference to a missed opportunity that is not dependent on the involvement of the individual experiencing the sensation.

Origin: The feeling of FOMO has been around since the beginning of time; however, its prevalence escalated with the creation of the Facebook upload. With social lives portrayed in rapidly–multiplying photo albums, individuals were able to better visualize exactly what they had missed out on. Thus, FOMO has hit an all–time high in the recent years.

Example: Girl to her friend: “Don’t feel badly that Jackie can’t come downtown tonight! She just has some serious FOMO, but you know she'll just photoshop herself into the pictures later!”
