A gay man who is very muscular, but whose personality is very effeminate and flamboyant.
My friend Jim is addicted to the gym. But he's such a flaming homo, which makes him a total muscle queen.

A muscle queen is a gay man who only desires to and exclusively sleeps with extremely and at times grotesquely muscular gay men.
I just saw my ex-boyfriend Gary with some type of bodybuilder. What did he do, turn into a muscle queen overnite?

A gay man who pumps iron every waking moment in order to be as physically appealing to other men as possible. Often lives in Manhattan's Chelsea section.
I found a great apartment on 23rd and 7th - immaculate, pine wood floors, rent control, and best of all, my new roommate's never home; he spends all his time at David Barton Gym. Total muscle queen.
