FOMS 

Fear of Missing Something. The emotion that compels you to join your friends when you know you shouldn't or really don't feel like it.

I was really tired from the night before but I got a serious case of the FOMS and went out anyway.

FOMS 

Fear of Missing Sleep; the fear that going to an event will lead to less sleep.

Instead of going to the party, Nathan's FOMS took over and he decided that he wanted to sleep instead.
