(noun)People who seemingly cannot function without the aid of a computer and as a result clog up social sites with useless spam-like content. This content often refers to farms, fishbowls, mob wars etc. The word is derived from Stephen Hawkings the quantum theorist regarded by many to be the smartest person in the world. However the reference is to fact that he relied on his computer to communicate due to a debilitating illness.
"I haven't been on facebook in a while because I have a couple of Hawkings filling the thing with a bunch of farmville wars crap"
