the dance you perform on gabbermusic, its kind of like skanking except for the arm swinging part and you do shorter kicks with your feet. this all compared with aggression makes for some good ol hakken.

Get the hakken mug.
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.
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.
