The explanation from the guy was okay as a whole but I could not agree with him about "tsundere" and "burikko".
The man got the "tsun" part right but he did not explain the "dere" part. "tsundere" is not just being rude to someone even you really like he or she, but also you have to become very nice sometimes as well.
About "burikko". "burikko" does not mean to fake your age but to act cute to someone even though you really act like ordinarily. However, I know it is hard for foreginers to understand these kind of stuff so the video will do for now.
