By saying Muslim ninjas, I am referring to the hijab thingy muslim women wear, especially the one that only shows your eyes (In other words, looking like this :ninja:).
By no means am I trying to provoke outrage about the labelling, it is merely a humorous and affectionate title given to the unfortunates in my school.
Personally, I think it makes life difficult as it restricts your field of vision and hearing abilities. Also, how do they travel?
