I actually disagree with some of them like tsundere and burikko. But I really want to focus on tsundere a lot, because Lika says that I am tsundere.
The basic of the basic, my defintion of tsundere is a person who cannot say their true feeling to the others because it is embarassing, so in the end, they say the opposite of what they actually want to say. So if a tsundere says "I hate you!!" it can be taken as "I love you".... but that is my definition. I might be wrong.
However there was no dere part to the explanation. The video only talked about the tsun part of tsndere and that is being harsh and rough on to people. Well, that gives some "moe" to people who are maniac, but that is not the actual tsundere. In order to become the true hardcore tsundere, I think people need to say harsh and rough words to people, but in the end they whisper, murmur or do what they actually want to do. The gap of being harsh and nice gives "moe" to more people than the tsun fans. So tsundere is basically saying and doing are two different things thing.
