Doesn't it mean "older fellow" as well?
Just when you think the shenanigans are over and you can safely follow the show, it turns around and kicks you in the balls. Again.
You only have yourself to blame.
watching this show as it airs and see how it is able to take stupider and stupider turns with each episode is one of the funniest experiences i've had watching anime.
I think it would be quite a coincidence to meet someone that looks like a mirror image but is not related.
