Circlejerk term used by groups of single girls to inflate their own egos and pretend that they're special.
If you're called a 'queen' by another girl, it's intended as a
compliment, but what it really means is that you're a prickly
punk ass bitch who thinks that her being single somehow makes her more empowered or relevant.
The cesspool of girls who use the term actively are
generally in high school and expect everybody to have respect for them despite frequently make pointed or rude remarks.
