Hakkened
When a cosplayer cosplays the opposite sex or only cosplays the opposite sex and viewers believes the cosplayer is that gender but they are actually the opposite. Basically the cosplay version of catfish.
Example:
Sally: Omg I'm in love with this cosplayer he is so sexy and he nails each character.
Emma: Sally I hate to break it to you but he is actually a she, you have been hakkened.
Sally: Omg I'm in love with this cosplayer he is so sexy and he nails each character.
