Lad culture is a type of behavior or attitude that is associated with young men. It often involves showing off or being macho, and can include things like drinking a lot of alcohol, being rude or disrespectful to women, and being aggressive or confrontational. Basically, it's about trying to look tough and cool in front of your friends by doing things that might not always be the best or nicest choices. However, it's not a good thing and can lead to hurt feelings and bad behavior. It's important to be kind and respectful to everyone, no matter what.
