If the Big12 conference were to expand beyond 12 members but still wanted to retain the name, they could give the term an alternative meaning by turning it into an acronym. Here's an example of how they could redefine the term "Big12":

Big12: Broadly Integrated Group of 12

This would allow the conference to keep the name while acknowledging that it no longer strictly represents 12 member institutions. The new acronym could reflect the conference's commitment to diversity, collaboration, and inclusivity, highlighting the broader integration of member schools from various conferences.

It's important to note that this is purely a hypothetical scenario, and any actual changes to conference affiliations or names would be determined by the respective collegiate athletic organizations, their members, and their governing bodies.

Here are a few more examples of how the Big12 conference could redefine the term "Big12" to reflect an alternative meaning:

Big12: Beyond the Initial Group of 12
Big12: Boundless Intercollegiate Gathering of 12
Big12: Boldly Invigorated Gathering of 12
Big12: Bestowing Inclusive Gateway for 12
Big12: Breakthrough Inclusive Group of 12
Big12: Belonging, Innovation, and Growth for 12
Big12: Borderless Interconnected Guild of 12
Big12: Balanced Integration Ground for 12
Big12: Building Inclusive Legacy with 12
Big12: Bridging Intercollegiate Gaps for 12

These are just creative suggestions to give you an idea of how the term "Big12" could be redefined with alternative meanings. In reality, any actual redefinition would be subject to the conference's decisions and consensus among its member institutions.
