Tsundere (ツンデレ, pronounced tsɯndeɾe) is a Japanese term for a character development process that describes a person who is initially cold (and sometimes even hostile) before gradually showing a warmer, friendlier side over time. The word is derived from the terms tsun tsun (ツンツン), meaning to turn away in disgust, and dere dere (デレデレ) meaning to become 'lovey dovey'.Originally found in Japanese bishōjo games, the word is now part of the otaku moe phenomenon, reaching into other media such as maid cafés, anime, manga, novels, and even mass media. The term was made popular in the visual novel Kimi ga Nozomu Eien.

As you've heard already, this is a anime stereotype where a character is violent and defensive at first, but sweet and affectionate in later on.
If you get a tsundere mad, you're best bet is running.

Japanese slang for one who is not nice and gets pissed off easily on the outside, but deep in the inside, is nice, caring, and gentle at all costs to the main character. It is usually used in anime/manga. The tsundere character usually shows his/her tsundere-ness in the later episodes/volumes/chapters.
Kagami Hirragi from the anime/manga Lucky Star is a great example of tsundere.

Someone who hates their infatuation (or just attachment) toward you and tries to hide any such feelings, leading to resentment and lashing out against you. Many tsunderes feel that their love interests are unworthy of them and/or may feel uncomfortable about being vulnerable in general. A tsundere may or may not become sweeter and more vulnerable toward the love interest as their relationship continues, depending on the health of the relationship. Their secret love may or may not be obvious to anyone else, but in fiction it tends to be, whereas in real life it tends not to be.
"Tsundere" is a combination of two Japanese terms: "tsun-tsun“ (to turn away in disgust), and "dere-dere" (to be lovey-dovey). The tsundere is a popular character trope in anime.

Tsundere describes someone who isn't very nice, but overtime changes to be nicer.

Or it could describe someone who deeply loves someone but tries to hide it from everyone.

Or it could mean some sadist bitch who beats the absolute shit out of the one she loves.

Tsundere is a Japanese term used to describe a persons personality. A Tsundere is a very cold and rude person when first meet them but slowly warms up to you. Though, a Tsundere doesn't show their affection very often, but you still know that they lobe you no matter what.
