Have you heard of the internet slang Tsundere?
Tsundere is a famous slang word used extensively on the internet world that has an amazing subdivision structure and the rules of its use are quite different.

Thus as a result the term is not elaborately explained or defined as what character in types can be described as tsundere, the term transcends species and gender.
Tsundere is often subjected to the creator’s point of view.
Its a portmanteau of the two words deredere and tsuntsun.
To explain what tsuntsun is, its mostly defined as aloof, pointed and morose, and on the other hand deredere is more explained as exhausted, lovestruck.
This concept os getting a lot of attention in Japan and there’s even a company that has opened a tsundere cafe in Akiharbar and its increasingly reflected in recent anime.
