The Egg Exchange Period, a joke made up by netizens, that is, girls do not understand the boys' physiological cycle, is a non-real adult joke. A lot of girls like to spit on the Internet aunt came how uncomfortable, etc., to bear a lot of pressure, etc., and the boys will only say "drink more hot water," etc., and so on, so the boys spit. And the boys will echo a sentence, "change the egg period will also be egg pain", "we change the egg once a month," and so on, but also said that the folds on the top of the egg is to change the egg scars blah blah blah, so that more and more people say, it has become a hot stalk. The male group is generally known as the "great aunt", and the girl's "great aunt" is also a physiological period of a name. Some men deceive women by claiming that they change their balls every year (or weekly or monthly in some versions ......), that boys know about it, that it hurts more than a girl's menstrual cramps, and that the procedure is expensive. This deception may be for a sense of accomplishment or revenge for women claiming not to understand the pain of menstrual cramps. A lot of boys like a discussion, as long as the girl asked such a thing, the boys will say it is true, it is a secret between the boys, a serious nonsense, but also the male collective deception of the girls of the incident, the boys of the genitals to move the knife, the most likely to be circumcision is just circumcision. At first, this terrier widely circulated in the posting bar, microblogging and other platforms, because more people said, some untouched girls believe, "Boys have to change their eggs once a month?", "Egg change period really exists," such a problem once the search index skyrocketed! The first time I saw this, it was a very good thing that I had a good time. In 2020, some female network anchor fans to joke with the anchor, in the interaction to the anchor to reveal their own "egg period", because the tone of a serious, resulting in pineapple Saidong, Zhou Shuyi, small Sophie and other anchors because there is no male friend (or pretend) around the beginning of the gullible, believing it, very effective program, so this allusion is more widely spread. So this allusion is more widely spread.
