A young straight biological male, particularly in his teenage years or early twenties, that bears a striking resemblance to an androgynous
lesbian. A heterosexual dude who, at first glance, is often mistaken for a boyish
lesbian. He is usually of smaller build, wears ambiguous attire, (ie: skinny jeans, Chuck Taylors) and cuts his hair into a faux hawk or other such
lesbian-trademarked coiffure. It might be said of him to have "
pretty" features, as well. Due to his tendency to be in touch with his feminine side, he is often pursued by fags, ex-dykes and fruit-flies alike, lending him to get a wider variety of ass than his douchebagy, meathead brethren. However, don't be fooled, my
fine lez sisters. The Dubian is indeed a bio-guy, therefore, if you're not into bio-peen, I suggest you stick to dating a bio-boi.
Jenny: What a fine looking butch that '
Bob's Big Boy' is, right? I'm gonna step to her and get me some.
Shane: Oh silly
Jenny! I hate to break it to you but that ain't no butch... Big Boy is a Dubian!
