Internet G

Someone who talks shit on the internet (Usually Myspace, Facebook, or Twitter.) but, won't say the stuff to your face because they would get their ass kicked.

From Nappy Boy Remix:

T-pain "You gunna hate on me on twitter right you an Internet G like Gigabyte"

Zero G internet

When you can’t find the answer online and have to look it up in a book

Bella went zero g internet when her web search’s failed to provide her answers; she headed for the book store.
