Rofl at HeroTex, thats the thing when you talk to "high classed pros". You start the conversation like saying something like what you said then of course they want to reply with an insult just as gruesome. When strangers meet in real life and try to insult someone they try and find things on there body (facial features, body structure/mass, etc) and use them as insults ~ the art of retaliation. But since maplestory is all pixel's, Ross as he is called used common sense most likey, that and generalization. He called you a nub cause thats what most people are in maple, and also called you a he cause most of maple are GIRL. If you met Ross in RL it prob would have gone down in the same manner. It's the human way of making themselves feeling bigger and better then any other.
To lazy to read all that?
Main Point: Bullying.
Pro's tend to not care for the lower class maplers that make up 3/4 of maple. They have there own world to deal with and they are tired with noobs (basically anyone who is not famous or their friend) randomly talking to them. Even if your on par with them, with out some sort of relationship there's nothing stopping them calling you noob.
Doesn't make sense? IDC cause its 5:26am (FMA marathon ftw)
