People with very empty lives that try to act tough on the internet, little realising they're making themselves look like total idiots. The only pleasure they have in life is signing into sites like YouTube and leaving stupid comments and sending people stupid messages. Usually they can barely spell or form a coherent sentence.
Internet warrior = Real life coward
Just look at the comments on almost any video on YouTube for an example of internet warriors.
The Real MCR: A very good band that is absolutely NOT emo. They have never claimed to be. Their lyrics are very deep, and thus MCR can appeal to a wide range of listeners.
The Fake MCR: A LYKE, TOTALLY EMO BAND I LISTEN TO WHEN i CUT MYSELF! oMg!!!11!
poser-emo: OMG My Chemical Romance is sooooo emo!
Normal people: Shut up loser.
