Facepuke (face + puke) is a derogatory term for the popular social networking website Facebook, mostly used by those who think Facebook merges individuals into one homogenous grey mass, subverts users' individuality and makes them reveal private matters to their "friends" most of them the've never met in person.
Logging into Facebook from work for just a quick "lurker" glance only to receive an IM from someone that knows you should be working.
I was at work today and I swear I was only on Facebook like 30 seconds when I got FaceBusted with an IM from a spouse asking, "Shouldn't you be working?"
Grandma - I finally got a facebucket! Now I can add you and send you virtual birthday gifts and invites to stupid groups to annoy the crap out of you. YAY!
Me -....yay?
