Standard basketball chants (such as "Air-ball" or "Sit Down") apply to the action of basketball games with a primary purpose of rattling the opposition. Unique, customized chants for teams at all levels of play (such as "Rock Chalk Jayhawk" for Kansas University) exist that promote school spirit and unity.
Occasionally a basketball crowd will chant to express its displeasure with a referee ("We got a rope, We got a tree, All we need is a ref-e-ree!"). An enthusiastic home crowd will not only cheer their team but also incorporate boisterous chants to create a decided advantage. Because the crowd is so close to the action, basketball offers perhaps the greatest opportunity of all sports for the crowd to interact and impact the game through cheering, chants and creating raucous energy.
