About

Do You Think Their Periods Ever Synced Up? or Do You Think Their Menstrual Cycles Ever Synced Up? is a catchphrase used in a series of posts and image macros alongside images of groups of people who presumably spend a lot of time together, wondering if their menstrual cycles synced up because they spend so much time together. The earliest known memetic use of the phrase was posted to Tumblr in August 2022, gaining viral spread over the following months. The meme is similar to the I wonder if they explored each other's bodies format.
