I know when I'm in the stands with a team, I'll stand and deliver a large amount of noise during introductions, then sit down during the match. If something exciting happens though, I've been known to stand up.

Go to a football game. Most of the time people sit, but when the running back breaks lose and gains major yardage, people stand. I see the running back breaking for the end zone analogous to tetras going slinky.
