What is the egg exchange period?

During the egg exchange, a joke made up by netizens is a boy's physiological cycle that girls don't understand, which is an untrue adult joke. Many girls like to spit out how uncomfortable their menstrual period is on the Internet, and they have to bear a lot of pressure, while boys only say things like "drink more hot water", so they spit out boys. Moreover, boys will echo the phrase "eggs hurt during egg changing" and "we change eggs once a month" and so on. They also said that the folds on the eggs were scars left by changing eggs. More and more people say this, and it becomes a hot stalk. Boys are generally called "uncles", just like girls' "big aunts". Some men lie to women that they change the ball every year (some versions say weekly and monthly ...), and that boy knows that it hurts more than a girl's dysmenorrhea, and that surgery is expensive. This kind of deception may be for a sense of accomplishment, or it may be to retaliate against women who say that they don't understand the pain of dysmenorrhea. Many boys like to discuss. As long as girls ask such things, boys will say it is true. This is a secret between boys, a serious nonsense, and an incident in which men collectively lie to girls. The most likely thing for boys is circumcision. At first, this stalk spread widely on platforms such as Post Bar and Weibo. Because too many people say it, some girls who have no personnel believe it. At one time, the search index soared. Since 2020, some fans of online female anchors have revealed to the anchor that they have an "egg-changing period" in order to joke with the anchor. The anchors such as Pineapple Saidong, Xiao Sufei were deceived at first because they had no male friends (or pretended to be) because of their serious tone. They believed it and had great effect, so this allusion spread widely.
