Trap

A term used in the anime community to describe the character archetype of male characters who dress and present themselves as women (not to be confused with transgenderism), a good example would be Chihiro Fujisaki from Danganronpa.
However, it should be noted that people in the LGBT community have criticized the word as people started using the term as a slur against trans women, along with it's relation to the gay/trans panic defense legal strategy.

Instead, you should try using the Japanese term "otokonoko" when talking about these characters.

"Man, I was watching this anime and there was this really cute girl character, but it turned out they were a trap and now I'm questioning my sexuality."
