FKW

Full Kit Wanker. Used to describe a sports fan dressed in more pieces of replica team kit than is necessary or acceptable for an adult. (note that children can never be FKWs)

For example, for football (soccer to the Americans amongst us) a shirt (jersey) is acceptable shorts and socks, however, make you a Full Kit Wanker.
