A word mainly used in Singapore and Malaysia, made up of the words 'Maple' and 'Retard', to show someone who plays MapleStory to such a great extent that he feels that the whole game is his life, and thus threatens people in other games to 'COME MAPLE LA! WE PLAY KS WAR LA CB' and that sort of thing. Mapletards also tend to stay in groups, so, when you see one Mapletard, it is likely that there are more nearby, and they will ALWAYS stand up for one another, since they like to attack en-masse, because their collective brain power is roughly equivalent to that of a cow. Which is impressive, compared to their own brain power, which can be compared to that of a prawn. It should also be said that if you do happen to encounter a Mapletard, it is important to either kill him, or otherwise dispose of him, since he will attack you for no reason, and will then proceed to KS (Kill Steal) you and start insulting your whole family, e.g, "NB COME LA! WAN FIGHT IS IT! I CALL MY GUILD COME! NB MTF CB! GO SUCK YOUR FATHER COCK LA!" This is just a sentence from a minor Mapletard. The hardcore Mapletards are much worse.
My God, that guy is such a mapletard. Why does he keep ksing all our mobs? Must be because he played too much Maple.
