I think the cheerleaders are there because 1) sticking that well-known cheerleader chant in the middle of this song kind of recontextualizes it and makes it sound like an s and m kind of thing, 2) even without them the song musically has a "jock jams" pump up for the big game kind of feel to it, which is hillarious when you pay attention to the lyrics and 3) it's just kind of funny that an actual cheerleading squad is now unknowingly singing on a song about gay oral sex (um, assuming that's a sample anyway).
