A Mapler is usually one who is addicted to the MMORPG Maple Story and plays it often. It was first used because Nexon used the term. It's often first said with a private server, for one who uses private servers a lot. Maplers often have something to really show their obsession over Maple Story, like having a plushie, or having a drawing of yourself in Maple Story form.
