People who lower their standard of communication on social sites (i.e. Myspace, status updates, Facebook, etc) to appear cool to their friends. They are usually followers who are insecure and need to appear cool to their friends. The use of fowl language is prominant and they use inside jokes that make them look "cool." For example, those who use words like "BITCHEN', or adhere to putting an s or z on the end of words that normally don't have those letters or not plural; HOTTAYS...you get the picture.
Jake was a cool guy, but around his friends, he's such a mooheef.
