O.O :) Such big words...

"Tsundere is a slang born on the Internet, and it is a word to describe the nature of female anime or game characters. Tsundere is a word combining two words, "Tsun Tsun" and "Dere Dere". Both terms describe attitudes of a person. "Tsun Tsun" is used for cold/blunt/curt attitude, while "Dere Dere" is used when a person becomes spoony in front of his/her lover."

Course, me not even sure tsundere is even being used correctly in that sentence.

But, see your point. Hope it's better now.
