Just like other poster mae says:
An attractive person of indeterminate gender who appears to have the "
XXY"
chromosome arrangement. Most often used to describe women who, though fashionable and made-up, look a bit manly.
To which I add:
Popularized by the
They Might Be Giants song about hermaphrodites. Unfortunately , a lot of people who heard the song didn't actually listen to the lyrics, and think 'sexxy' is just a synonym for sexy.
As before:
Did you see the woman in the skin-tight
Versace dress with the big
adam's apple?
SeXXY.
