Why is the word 'Ninja' offensive?

[MANGLER]

I do. Being an ugly deformed monster-child bastard is one of them.

I'm sure you'll be ok man.

WTF? You got problems man.

You got an admirer, mang. You are the most laid back person on this boards, seriously. Off topic but I was wondering what boxers do you actually like(other than Juan)? Just asking because you are one of the very people I have ever seen not nut hug a fighter. For a while I thought you were a SSM fan but I'm not even sure about that.
