A male that is heterosexual but has all the emotions and mental capacity of a woman. In extreme cases, over complicating the most simple situations. Lacking in masculine social skills, confused on why women don't get them, and % 100 guaranteed to fail in any dating environment.
"Did you hear that guy rambling about how women don't get him and he cant find a date on Tinder?What fucking mansbian!"
