guydar

An ability to identify an individual as a man or a woman. This is often used in cases of crossdressing, or cases where one gender will bear close resemblance to the opposite.

Boy: Hey, that girl on your binder's hot!
Girl: Girl?! You mean Shinya? Shinya's a dude, man. Looks like someone needs a new guydar.
