FMO 

Fuck Me Over.

To be stunned/shocked/pissed off when something really bad (and very often ill-timed) happens.

Computer: "Microsoft Word just decided to delete you 20-page document and it's content."
Me: "FMO!"

Fmo 

A type of music that is almost like emo but most of it is about relationships and fucking. Almost every word in it is the word fuck. A lot of it is about how beautiful fucking is.

One actual lyric in an fmo song is "oh my god you dick is so beautiful I'm gonna go and cut myself!"

I like is listen to fmo
