I don't know, really. I wear feminine clothing(though they're very atypical outfits). I have no interest in TV sports. I can belch my alphabet. I like to fight for entertainment(but find that once you pass your mid 20s, few want to play anymore).
In my 20s, when I wasn't so hermited, I'd socialize with folks, and eventually "you're not really a girl, are you" would drop.
I consider it a parlor trick.
