People who are always on Facebook but never "do" anything on it. They are too cool to add any updates, photos, links, or comments, or make any other contributions, but somehow they know everything everyone else is doing.
You meet up with a Facebook SneakMouse and over the course of your time together (coffee) they will reference several Facebook posts, photos they saw, or links. You're thinking, 'but hey, you're never on Facebook'....
Ah-HA! They totally are, but are just too cool to admit it.
On top of that, 'catching-up' over coffee is a one-way conversation because the Facebook SneakMouse already know everything you've been up to through...you guessed it...Facebook.
They live underground so you can't ever see them coming, and they have eyes all over so they can see you before you see them. Coined by Sam of Wisconsin.
