Hype culture is when people get really excited about something and they want everyone else to be excited too! It's kind of like when you get really excited about your birthday party and you want all your friends to come and have fun with you.
Sometimes people get really excited about new things that are coming out, like a new toy or game or movie. They might talk a lot about how cool it is and get their friends just as excited to try it out. Sometimes people even camp out or stand in long lines to get the new thing first!
Hype culture can be fun, but sometimes it can also be a bit too much. Sometimes people get so excited that they start to believe that the new thing is the best thing ever, even if it's not really that great. And sometimes people can get really upset if something they were hyped for doesn't end up being as good as they thought it would be.
So, hype culture is about getting excited and sharing that excitement with others, but it's important to remember to keep our expectations in check and not get too disappointed if things don't turn out exactly as we had hoped.
