About Something 101

常常在歐美影集或電影裡面聽到"something 101"，剛開始聽到的時候蠻疑惑的，後來看多聽多就知道原來是在指某個東西的基礎或是第一次接觸到的新事物，從網路上找了對於101的解釋：

The definition of 101 is “basic” or better yet – “introduction”. It is usually used when someone gives or asks for a “beginner guide” in order to teach or learn something new. So, “xxx 101” means an introduction or beginner guide for “xxx”.

Sometimes 101 meaning is altered a bit to reflect stupidity of someone and not just lack of knowledge.

是說通常人們在學習新事物的時候，會說"xxx 101"來指這件新事物的簡介和入門，還有些時候意思會被改變成指人的愚蠢，而不是缺乏知識。

第二個意思感覺比較少見，之後看電影或影集的時候，可以多多注意一下。當然人們使用101的起源也是令人好奇，為什麼要用"101"而不是用其它的說法來代替，網站上是這麼說的：

People invited all kind of complicated reason why 101 means introduction, but the truth is very simple – it is thanks to collage.

In most collages around the word (aside from UK) courses’ numbers are 3 digits numbers when the first course number is 101 and the rest are of higher numbers.

Usually the first courses in collages are basic courses or introduction courses. Therefore, usually the basic / introduction courses’ numbers were 101.

This is how 101 became a code for introduction courses, and was later generalizes as an expression for all kind of introductions.

簡單來說101的起源是來自於大學，通常在世界各地的大學課名會用三位數字，所以101就會是第一門課，而第一門課通常都在介紹基礎和入門的知識，因此101後來就被當作指稱所有個事物的入門。

雖然101是從大學起源的，但絕對不是只侷限在學術方面的使用，有很多電影和影集常常在奇妙的地方有使用到，像是：

True Blood 6x06 (50秒左右) → glamour 101

Monster University → scaring 101

甚至是歌曲中也會出現，以下歌曲為18禁，慎入：

Lick it by God-Des & She → pussy eating 101

這是一個蠻有趣的生活小用語，可以嘗試用用看，或是在看電影和影集的時候注意裡面的用法。
