I don't know anyone in specific who uses those terms, but I know what you mean about the girls who think everyone is just "hatin'" on them. Acting like that isn't cute, and it doesn't make you look cool. It makes you look ignorant and uneducated, and it makes you look like you have absolutely no class.
I feel sorry for those people because they're living in a dream world. They're delusional, but that's what makes America great. You have the right to be delusional. I know it's annoying to see them prance around, but the best way to handle them is to laugh and mock them.
