Bro culture is when a group of people (usually men) act in a certain way that involves things like being tough, showing off, and sometimes being mean to others. It's like when boys at school brag about who's stronger or faster or who has the coolest toys. Bro culture sometimes involves things like drinking a lot and doing dangerous things to show off. While having friends and being confident is important, bro culture can sometimes be hurtful and make others feel left out or bullied. So it's important to be aware of how our actions can affect others and try to include everyone!
