look up any word, like hipster:
 
1.
a man or woman who is obnoxiously effeminate in a group setting
That bitch is such a plaza queen, everybody within 10 feet cleared the dance floor.

2.
Pretty much a huge, annoying bitch. Someone who sells themselves out just because. A plazaqueen is a boy or girl who acts like a stubborn, spoiled brat.
Not someone you want to be friends with.
"I swear, she's such a fucking plazaqueen."
