Basically, a couple consisting of a very feminine-looking/acting boy and a very masculine-acting/looking girl. Need not be romantic, but usually is. Often comes from pairing the Action Girl with the Non-Action Guy and with doses of Cross Dresser, Bifauxnen, Ambiguous Gender, Attractive Bent Gender, Dropped a Bridget On Him, Viewer Gender Confusion, Dude Looks Like a Lady, Even the Guys Want Him and Even the Girls Want Her. Common in Gender Bender and Freaky Friday Flip series. Occasionally, House Husbands and their wives will fall under this trope.
