FONSI

"Fear Of Not Staying In" - Opposite mindset of FOMO, where you don't have the Fear Of Missing Out, but rather dread having to leave your place to do social things.

"I already confirmed "YES" to be there, but man, does that couch look really inviting. Call it a case of FONSI - I'm seriously conflicted."

FONBI 

FEAR OF NOT BEING INVITED - Similar to FOMO, but it is the fear of not being invited to an event or a gathering. Many people won't mind as much missing out, as long as they were invited in the first place.

When I couldn't make it to the best birthday party of the year due to a prior engagement, I didn't get FONBI and didn't mind missing out on all the fun because at least I was invited to the party .
