What is it called in College Basketball when the student section jumps up and down, and screams ohhhhhhhhhhhhhhhhhhhhhh, when their team is in defensive possesion. Why do they do that? Who invented that? I think that thing is cool and exciting, and I want to do that when I go to college. Go in your college's basketball game in the student section, and jump up and down, and yell ohhhhhhhhh. That is fun and exciting to do. |||thats like the cameron crazies thing
