two in the pink one in the stink

关于英文“two in the pink， one in the stink”，是什么意思？还请解释一下原因，谢谢。~

初学短语的时候还是直白点儿比较好……自己用的时候再委婉些吧
以下是Quora解释的原文：It's a method of a fingering a girl's orifices for maximum effectiveness. Two in the pink refers to putting two fingers in her vagina (pink). One in the stink refers to putting one finger in her anus (stink). It is usually done with the index and big fingers in the vagina and the little finger in the anus. Another expression that's used to refer to the same is "Two in the goo, one in the pooh."
就是两根手指插进阴道，一根插进肛门的一种达到性高潮的方式

这句话表达的是一个手势，这个手势在国外是具有性暗示的，所以太污还是不要了解的好

两根手指插前面一根手指插后面，只能告诉你这么多了。。。

两个在粉红色的一个在臭味

两个粉红色当中有一个在发臭

两个粉红色的一个散发臭气（精）（锐）环东
