In English, there is "too chicken", meaning cowardly. but no "too cow", so it's basically a culture thing, and you just need to know which animal is used and which one is not.

Yeah, I hadn't thought about that. Using an animal name as an adjective happens in English too. Thanks!

May be there is "太猪了", but I never heard anything like "太鼠了". And overall, "太牛了" is an alternative of "太牛逼了" like the other answers stated.

Echo what @Bolu said, I honestly have never heard of "太鼠了” or "太猪了” as a native speaker who spent most of my time in China mainland. I think "太牛了” is a short version of “太牛逼了” which literally means cow's v-word. In Taiwan, the counter-part expression will be "超屌的”，which refers to males' penis. In English, we have "kick-ass" and "ballsy" as well. Not sure why people tend to use sexual parts to express greatness of action by a person.

<p>It came from <strong>牛逼</strong>. <strong>牛逼</strong> means cow's genital orginally and it is derivatized into <strong>impressive</strong> due to it's wide. Many people are saying it even it's bad meaning. You can both use <strong>太牛了</strong> and <strong>太牛逼了</strong> though.</p>

It's so confusing that you accept this viewpoint, 牛 never comes from 牛逼. The single character 牛 with the meaning **awesome** is much more earlier than the modern word 牛逼.

It came from **牛逼**. **牛逼** means cow's genital orginally and it is derivatized into **impressive** due to it's wide. Many people are saying it even it's bad meaning. You can both use **太牛了** and **太牛逼了** though.

At first, it was 吹牛皮, which means blowing up the cow skin. 吹 means blow up and 牛皮 means cow skin.

Long ago, butchers blow up the pig skin to shave hairs. However, a cow is much bigger than a pig. So, when someone says he/she is able to blow up the cow skin, he/she must be talking big (吹牛皮).

Sometimes，speaking rudely sounds cool or more impressive. So, 吹牛皮 turns to 吹牛逼. 牛逼 means cows' vagina. We use 逼 but not the correct Chinese character, because 牛逼 sounds more acceptable. It's just like shot and shit.

吹牛逼 means talking big, while 牛逼 means "real big". 牛 is short for 牛逼.
