These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Hollywood Pudgy: One of the cheerleaders from the first movie (and the third one as well) is repeatedly criticised for having a rather large backside. She's not that much more heavy than any of the other girls on the squad.
In Name Only: A musical titled Bring It On went on tour in 2011, and appeared on Broadway for a spell in 2012. Though it was advertised as Bring It On: The Musical and is about cheerleading, with some racial elements thrown in, it otherwise has nothing to do with any of the movies.
