The character hen is catch-all for queerness as a peculiarity-it does not carry an explicit sexual reference.

In sexual contexts, it carries additional meanings of ' perversion' or 'abnormality', especially when used as an adjective : 99 in these uses, it is the shortened form of the phrase hentai seiyoku ( 変態性欲) which means 'sexual perversion'. Hentai is a kanji compound of 変 ( hen 'change' or 'weird') and 態 ( tai 'appearance' or 'condition'), and means 'metamorphosis' or 'transformation'.
