The mentality of some hijabi's, in which they feel as if they are superior to other non-hijabi muslim females.
The Hijabi Mentality makes a lot of hijabi's demand respect, only due to the fact that they wear a hijab. Often times, some hijabi women may not be the greatest of muslims, yet they still have the attitude that non-hijabi's are inferior, even if the non-hijabi is more religious than the hijabi.
Example: Please do not treat her like that, she is a hijabi (but not saying the same thing for other non-hijabi muslim women).
Please keep in mind that not all hijabi's have this mentality, there are a lot of great hijabi women out there. But with every good thing, comes at least a few bad things. Also, we should never judge our muslim brothers and sisters, wether they are very religious or not, and wether they were the hijab or not.
