Loud, obnoctious, slutty cloths, and thinking they are all gods gift to men
OP is not here but I will give away a secret. That person you have never meet but think she is arrogant and full of herself, usual is not. Even if you think she is loud, obnoxius or wear "slutty" clothes.
May be you want to make her into a bad person to make yourself to feel better, but it does not mean it is the truth.
