I don't get FOMO often, but I get FOMO from not taking advantage of when grainy, flash-heavy mirror pics were in.  Don't get me wrong I take a lot of mirror pics, but never in front of a toothpaste, snot, water, splattered mirror (the corners weathered from neglected bathroom fan use). Not once did I snap a flash heavy mirror pic with my enV Touch or even LG flip-phone. That doesn't sit well with me.
