A cap with a visor,which may be worn either in the front or back; a baseball cap. Typically worn as ordinary casual headgear by men,not meant to be impressive.
Kenny,Kevin,Tom,Jamie,Matt,Robert,William,Harun,and Jim are all content to wear plain,simple ball caps. How dull and mediocre. Oh,well,as long as they're contented.

Similar to the teabag, in this instance, the male places his genitals on top of the head of a female partner, (or a friend to be embarrassed). The balls rest on their head as if they were a cap, the penis of course is the Bill of the Ball Cap.
That asshole went out on a date with my sister, I came home and they were watching TV on my couch so i just gave him a ball cap.
