What SONG is this? SPORTS THEME? easy points!!?

well its not really a song but its like a victory theme that the croud sings when their team wins.. they vocalize it, it goes kinda like " aye aye aye ooo ahhhh, ahhhh ooo ahhh aye aye aye ooo ahhhh" but its all vocalized by the crowd, like at the end of the Celtics championship game the croud vocalized that song as a "victory chant" or somethin... if you have an idea can you please answer! thanks :)
