You think all the energy in Phog Allen Arena is spontaneous? Sorry to inform you Kansas has one of the most manufactured environments of them all. I'm not saying that they don't have good fans who are passionate and knowledgeable, but just about everything the fans do is scripted and heavily influenced by playing very loud music and a very loud announcer.
Even in the clip you had in your post, the students know they are supposed to jump up and down at that moment. Or to put it in your words, "look a crowd all jacked up with corny *** music and moves that a daycare for 4 years olds could create."
