An actual acronym among the mass of Millennial abbreviations--WTF, OMFG, ad nauseum--mistaken as such.

The word fomo (not to be mistaken with its homophone, Faux-mo) stands for “fuck off; move on.” Its lack of semicolon is comparable to other minor details implied—though not included—in the transference of countless other phrases to acronyms. ex: the word “of” in OPEC.

Created as an addition to the lexicon of netspeak, fomo is ideal for a thread in which some twatrot insists on saying the same thing with slightly different phrasing under the auspices that this time s/he’ll make everyone else “see the light.” A mod or community member who’s had enough might chime in ‘”Dude, we all heard you. Feel free to fomo. Matter of fact, I insist.’

However, the inception of fomo came about in direct response to some Millennials with the attention span of gnats, who—despite the fact they’ve never read an entire book in their lives—still feel the inherent need to exert the time and energy to snark that a 5-paragraph post was tl; dr.
(via chat):

‘Fecking shit. I spent all morning writing a blog just to log-in tonight and find four lame-ass comments in response!’

‘dang, maing. 4 cmnts means u affected 4 ppl. imagine how I feel 2 get cero?’

‘Yeah, well imagine how *I* feel when all four say ‘tl;dr’?’

‘worrrrrst. it's like, whyd they feel the need 2 tell u that? bitches need to just fomo—and fast.’

‘Agreed. I don’t have to stop some author in his tracks and go, ‘Hey, I didn’t read your book.’

Totez.’

‘O.K. You can speak in English now…”

A disorder that Norman "Nick" suffers from. He cannot miss out on anything or it will just continuously eat at him forever. He will try to go to any extent to ensure that he does not miss out on anything because he doesn't want to be the one person who wasn't there.
Norman "Nick" initially said he wasn't gonna come to LFK last weekend but after his roommates left, he got hit with mad FOMO and decided to say "F my chem test" and just leave at 8 pm that same night to not miss out.
