Putting him back in his place, our triumphant Twitter user hits back: “You’re TWENTY FOUR and you DON’T KNOW THAT VAGINAS BLEED?”

At which point he calls her “dumb” and attempts to save face by saying that as “the body shuts down over night” he didn’t think getting a period was possible. Someone hand this man a biology textbook.

Not only did the woman brilliantly call him out for calling her dumb and the idea that “our uterus waits for us to wake up,” but she also helpfully shared the conversation for all to see, not only supplying us with a much-needed chuckle, but giving the women of Twitter the chance to give him a good roasting, too.

Our favourite response came from a Twitter user Lisa, who says: “Yes. It is true. When we sleep, our breathing comes to a complete stop and our hearts stop beating. Our soul is then transfered to the cloud where we have our dreams stored. Your body will know when it’s time to get up and will call your soul back. The human body is amazing.”

Another shared another anecdote, writing: “My sister has an ex that though we only bled when we went to pee!”

Which, in turn, encouraged a flood (sorry) of other hilariously similar stories, which we’re gonna leave right here for you:
