Loved the video. From the general lack of enthusiasm from the surrounding girls when each set was going down the makeshift runway I get the feeling that most of these girls don't really like each other.
Between this and the RPD Blurred Lines video, this might be my favorite Houston summer in a long time.
I didn't notice or read anything at all into it; they may have just been thinking about their specific routine. There's also the thrill of working on a Friday afternoon in a non-game, non-TV setting in the offseason for whatever crap wages professional cheerleaders get. I think the lack of variety in their moves was more noticeable, confirms that girls are picked on body type and just learn their dancing on the squad.
