One who avoids facebook due to the saturation of the menial tasks people describe in detail with poor grammar/spelling/diction. Nobody is as interesting as facebook would indicate.

I am a full-fledged facebookophobe, I don't give a shit how tasty your chipotle burrito was. I also think self-shots make you look like you live in your toilet.
