What meaning does the nickname "Kyon" has? In the Melancholy of Suzumiya Haruhi, the main character's nickname is "Kyon" (キョン). From the novel, the origin of the name is explained:


  By the way, Kyon would be me. My aunt was the one who first called me
  that. A few years ago, my long-time-no-see aunt suddenly said to me
  "My goodness, Kyon has grown so big!" My sister thought it was funny
  and also started to call me Kyon. After that the rest is history— my
  friends, upon hearing my sister calling me Kyon, decided to follow her
  lead. From that day on, my nickname became Kyon. Damn it, my sister
  used to call me "Onii-chan"!


Kyon does not seem to like the name very much. Also, his sister "thought it was funny". This makes me wonder what "Kyon" actually means. It it has no meaning at all, why would Kyon's sister find it funny?

Does "Kyon" mean anything?
According to RomajiDesu, it's a species of barking deer. It's humorous because the "n" on the end makes it sound feminine. Onii-chan is a token of respectful affection,  in contrast.

It's the contrast from being called (in all sincerity) "dearest big brother" and "Bambi"
