About streaking

Streaking is the act of running naked through a public area for publicity, for fun, as a prank, a dare, a form of protest, or to participate in a fad. In the western world, streaking has since the mid-20th century most often been associated with college students and sporting events, where it is intended as a harmless attention-seeking prank. Streakers are often pursued by sporting officials or the police.
