Dot-commer

[Greta]

An online [shit-talker], who brazenness ends where his keyboard does. One who will not actually confront an [adversary] in real life, but will instead attack anonymously (see: [formspring]) or from an incredibly far distance, likely from another state, or perhaps even further than that.

One who gives the illusion of grandeur, wealth, influence, or popularity online, who is actually the opposite IRL.

One who gains popularity or influence via internet networking sites, but nowhere else.
