What does the egg exchange period mean?

During the egg exchange, a joke made up by netizens is a boy's physiological cycle that girls don't understand, not a real adult joke. Many girls like to complain online about how uncomfortable their menstrual period is, and they have to bear a lot of pressure, while boys only say things like "drink more hot water", so they spit out boys. Boys will also agree that "changing eggs hurts" and "we change eggs once a month" and so on. They also said that the wrinkles on the eggs are scars of the eggs becoming Balabala. More and more people say this, and it becomes a hot stalk. Boys are generally called "uncle" and girls are called "big aunt", which is also a title of physiological period. Some men lie to women about changing the ball every year, saying that boys know it, that it hurts more than girls' dysmenorrhea, and that the cost of surgery is high. This kind of deception may be for a sense of accomplishment, or it may be to retaliate against women for not understanding the pain of dysmenorrhea. Many boys like to discuss. As long as girls ask such questions, boys will say it's true, and the secrets between boys are serious nonsense. It is also an incident in which men collectively cheat girls. The most likely thing is circumcision. At first, this stalk was widely spread on platforms such as Post Bar and Weibo. Because there are too many people talking, some unsuspecting girls believe it. Like "Do boys change eggs once a month?" And "does the egg exchange period really exist?" 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, Zhou Shuyi and Little Sophie were cheated at first because they didn't have any male friends around them, and the effect was very good. So this allusion is widely circulated.
