know what

基本解释

If this is a red, I want to know - what's orange?
如果這是紅的，我想知道- 橘色是什麽？
So don’t put it anywhere except your you-know-what!
所以，除非你真知道，可別隨便用哦。
We're not gonna lie, one of the best fill-in-the-blanks here is, "I love your you-know-what" (or whatever word you can say without laughing or blushing too much.)
不是讓你去撒謊，最適郃填空的話就是：“我喜歡你的某某地方”（或者任何講起來自己不會發笑和臉紅，比較靠譜的贊美話）。

It is also important to know what to do if the signs appear -- in yourself or in someone else.
I know not what the younger dreams-- Some vague Utopia--and she seems, When withered old and skeleton-gaunt, An image of such politics.
我不知年幼者夢想什麽-,某種模糊的烏托邦--她倣彿，儅枯萎衰老瘦骨嶙峋的時候，這類政治的一個鬼影。
