What is what does saturdays are for the boys mean?

"Saturdays are for the boys" is a phrase that originated among groups of male friends in the United States. It refers to the belief that Saturdays should be reserved for time spent exclusively among male friends, engaging in activities such as watching sports, playing video games, or simply hanging out and bonding. The phrase can also be used more broadly to express a sense of camaraderie and brotherhood among men. However, it has been criticized for excluding female and gender non-conforming individuals from social activities.
