I don't think this is a goof
Listed on the goofs page:
Errors made by characters (possibly deliberate errors by the filmmakers): In the first opening cheer-leading scene, Jessica runs off to the side and says, "Ready, Hindenburg?". The character's actual name, however, is "Hildenburg". This mistake is not made by any other actors
This is definitely intentional and not an error. Hindenburg is the name of a rather infamous blimp. So I assume she called Hildenburg this as a jab at her weight. I thought that would have been obvious :P
