Arjun

Ok I just have to give this definition because most you are terribly wrong about it. Arjun word actually means simple minded, fool, simpleton(light criticism). In Indian epic Mahabharat he was the only warrior who don't want to fight after reaching battlefield. In our old books people are named by their qualities. We have Bhim(big), yudhisthir(steady even in war), krishna(dark). But you'll now have meanings like clear minded, fair which are positive variation to 'simple minded'. It happened cause he was the 2nd hero of our epic book, brave, skilled archer plus loved by girls so people threw good light on him. Think of a game Japanese whisper(or maybe Chinese) where words change person to person according to what they think.
