The curious way that characters in Harry Potter Fanfiction can be not gay but still in love with a man, in popular practice this is a way to explain how Harry Potter has never been attracted to a man before and not really many women and is still attracted to Severus Snape. Also Severus Snape fans claim this title.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.
