it's possible the whole thing wasn't really explained to them. the girls just kinda followed him and danced awkwardly while laughing with each other in the ring. perhaps they just weren't familiar with the character and didn't hear the "hoooooo" part, but i thought the whole act was pretty clear and was surprised everyone was into it. it seemed like somewhat of a family/community event too because they were raising money for the school's athletic department or something. it was one of the last couple matches though, so maybe no one wanted to raise a stink when they saw everyone having a good time and the thing was winding down, but it still baffled me in the moment.
