How to make pro igns:
1: Find a verb that has literally nothing to do with your life, interests, in-game class, or maplestory in general (For this example we will use "rewrite"
2: Add obscure ending to it that removes all meaning from the word in order for it to make no sense in any context. A couple of these are -ify, and -ingly. (We now have Rewritingly)
3: Make your character with your pro IGN! People will look up to you for having an IGN as a real word!
