The wearing of a g-string, thong, or the like - the wrong way around. Either back-to-front. Or, more often, sideways. Often occurs when getting dressed while intoxicated.
An otherwise nicely dressed woman is unfortunately showing off her g-string... only something's not quite right there... ooops... that's one hell of a reverse commando... and a great camel toe while she's at it!!
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
