An unofficial annual celebration held on November 3rd, where straight men spend 24 hours acting as each other's boyfriends. The day encourages platonic affection, camaraderie, and playful exploration of same-gender relationships, allowing bros to experience a different dynamic without any romantic pressure.
"Dude, it’s November 3rd! Time for Be Your Bro's Boyfriend Day! Let’s hit the town and show some love!"
"On Be Your Bro's Boyfriend Day, we went to brunch, held hands, and watched a rom-com—it was surprisingly fun!"
