obscenity 的畫面可以想成一條線。這條線是大家心裡「還可以接受」的界線。越過去的東西，會讓人不舒服、覺得被冒犯。這個字講的就是越線的那個東西，或越線這件事本身。線畫在哪裡由人決定，所以這個字後面常常跟著一場爭論。From the word’s history
The word is obscene plus -ity, from Latin obscenitas — the noun that names the quality of being obscene.
這個字是 obscene 加上 -ity，來自拉丁文 obscenitas。-ity 在英文裡常把形容詞變成「那個性質」，像 pure→purity。所以它本來就是在指「越線的那個性質」。
