What does cfb mean in ourworld?

That’s a great question, and the answer depends heavily on the context, but in the United States, one meaning is overwhelmingly common.

In almost any general conversation, especially online or related to sports, CFB stands for College Football. It's a massive part of American culture, particularly from late August through January. The term refers to the games played by large university and college teams, governed primarily by the National Collegiate Athletic Association (NCAA). For millions of people, Saturdays in the fall are completely dedicated to watching their favorite teams play. The rivalries, traditions, and passionate fan bases make it a huge spectacle, often just as popular as the professional NFL.

Of course, in a highly specific technical field, an acronym can mean something else. For example, in engineering, it might refer to a "circulating fluidized bed." However, that's incredibly rare in everyday language. If you see someone casually mention CFB online, you can be 99% certain they are talking about the touchdowns, rivalries, and championship dreams of American college football. It's a true cornerstone of our sports landscape.
