Thats not what being a fanboy is. Fanboy Someone far beyond a simple fan. No, not the tye of fan which keeps people cool.
An arrogant person who goes into an outburst every time something he likes is questioned. Fanboys usually acuse others of being fanboys. Usually use 1337 and swarm MMORPGs. Fanboys caused alot of fallouts between people when they started arguing about consoles. If you insult something that a fanboy likes, he will spam your computer up and try to insult something that you like. Most words a fanboy uses are in 1337 or end with 'X0RZ' and they spell the work 'the' as 'teh' because they think that it is 'teh ro><0|2Z!!!' e.g. Counterstrike is teh rockxorz!
Fanboys usually use the word 'own3d' if they beat someone. Another annoying feature of a fanboy is that if he is loyal to a console, he usually goes to rival console forums and spams the place up with inults about how his console is 'better'. They take the 'console war' very seriously, as if it's a real war.
