When a pro player plays something like DotA or CS, constantly owning, and then some random noob comes into the room or netcafe, the pro player suddenly starts to die and lose. This is caused by noob aura. It is very serious problem. The only way you can get rid of it is to kick the noob out of the room, netcafe etc etc. When you do this, your pro skills are returning to you instantly and you start to own again.
Pro player(playing dota): Double kill! Oh yeah! Triple kill!!! Oh yeah!!
Noob enters the netcafe: Hey guys. What's up? Wow you play dota! I have to watch!
Pro player: OMFG I DIED! FFS! SOMEONE KICK THAT NOOB OUT, HE IS SPREADING NOOB AURA! FAST BEFORE WE ALL START TO SUCK AS HELL.
Noob gets kicked out of netcafe.
Pro player: OH YEAH DOUBLE KILL AGAIN! RAPE THEM! GO FOR THE RAX!
