"Ok boomer" is something that some people say when they feel like older people just don't understand them. It's like when you tell your mom or dad something you think is really important, but they just say "ok" and don't seem to care. When people say "ok boomer," they are basically saying that they think older people don't get them and their views. But remember, it's not always polite to dismiss what someone says just because they're older than you. It's better to try and explain yourself and understand where they're coming from too."
