I hope its not a legal thing. PlayBoy Sasuke is a good ninja, the only thing someone could harp on is the term PlayBoy in his name. But they also call Tony Stark a play boy in the Avengers, and that is a Disney movie. (Marvel is owned by Disney so its technically accurate)

My point being 99.9% of people don't have a probem with this term, so I wonder what could be causing this...
