vulgarity gap 粗俗代沟

Vulgarity gap is a disparity in the tolerance for vulgarity between generations or communities.

粗俗代沟（vulgarity gap）指两代人或两个不同的群体对于粗俗行为的不同包容度。

It has become a cliché to posit that millennials/Generation Y have an ease with crudeness that distinguishes them from their parents' generation. Millennials are perfectly comfortable with language and humor that makes their parents' generation blush. Similarly, things that in one language are quite vulgar, are not so gross in another.

说千禧年一代（即80后）与他们父母一代最明显的区别是他们对粗俗行为的见怪不怪，这已经不是新鲜的观点了。那些会让他们的父母脸红的语言和笑话，千禧年一代却觉得没什么大不了。类似的情况是，在一种语言里很粗俗的事情在另一种语言里却没有那么不堪。
