Ah, I understand. You would refer to me as "han" because you can guess it by my nick, whereas I can't tell anything about you by just looking at your nick.
Hmmm... The Swedish "han" is of the same origin as the German "Hahn" which means "rooster", similarly "hon" equals with the German "Huhn" meaning "chicken", and they both can be referred to as "hen" both in Swedish and in English. Someone must have had a gallinaceous way of thinking.
