extronet 

A person who is an obnoxious, misguided, and intolerable extrovert online, but a true introvert outside of the web. These people feel brave and boastful, but are true cowards and have no original thoughts of their own.

Konstantine was online last night reading the comments he received on a post he made about neutering feral pets and became furious when he discovered the mean-spirited and overly political hate speech directed at him. He realized it was from his mild-mannered coworker Patrick. He made a plan to confront this extronet at work in order to get him to pee his pants.

extranet

A private network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers or other businesses. It can be viewed as part of a company's Intranet that is extended to users outside the company (eg: normally over the Internet). It has also been described as a "state of mind" in which the Internet is perceived as a way to do business with other companies as well as to sell products to customers.

extranet meme 

(Or outernet meme) A meme that gained popularity by distribution outside the internet.

The word "extranet" is a retronym - a word used to describe an object or entity that has been superseded by a new kind of thing, where the original object or entity was not previously described using the new word.

Examples: email and snail mail (snail mail being the retronym for ordinary "mail"); quantum mechanics and classical mechanics (before the discovery of quantum mechanics the way matter interacts on the superatomic scale was simply "mechanics"); and finally, internet meme and extranet meme.

Examples of popular extranet memes:

Keep Calm and Carry On

Pretty much any idea that became widespread without using the Internet.
