A NFL or collegiate cheerleader, or other sports-related sex object. A jock-a-bimbo is more than just a cheerleader as she is more explicitly sexual than implicitly so. The function of the jock-a-bimbo is purportedly to cheer for a team but her latent function is to perform in a sex show adjacent to the athletic competition that exudes a sexuality that underscores societal male hegemony.
The Dallas Cowboys cheerleaders are arguably America's leading jock-a-bimbos. They are potent sex objects that appear both on the field and regularly on TV and other media. They comprise America's Sex Team.
