Queerism - Manxious

adj: a fear of a loss of one's own masculinity, a fear of effeminate behavior or being associated with effeminate behavior.

ex: "I know Blake's the only straight guy in this gay bar, but why is he in the corner holding onto his man purse and acting all manxious? It's not like he's gonna turn gay if someone hits on him. Go get him a mojito, tell him to relax, and have a good time!"
