Showboating
Based on the supposedly gaudy look of showboats, the term "showboat" also came to mean someone who wants his or her ostentatious behavior to be seen at all costs. This term is particularly applied in sports, where a showboat (or sometimes "showboater") will do something flashy before actually achieving his or her goal. The word is also used as a verb. British television show Soccer AM has a section appropriately named Showboat, dedicated to flashy tricks from the past week's games.
Oft-cited examples of showboating include Leon Lett's grocery-bag-carrying of a recovered football (which was then swatted out of his hand before the goal line) in Super Bowl XXVII; Bill Shoemaker's standing in the saddle before the finish line of the 1957 Kentucky Derby, costing him the win (some sources say he merely misjudged the finish line, with another jockey ahead of him not standing up then); Lindsey Jacobellis's grab of her snowboard which caused her to crash right before the finish of the Snowboard Cross final at the 2006 Winter Olympics, costing her a first-place finish and a gold medal (she got a silver medal instead); and Usain Bolt pumping his chest before winning the 100m final at 2008 Summer Olympics, likely adding one or more tenths of a second to his world record time of 9.69 seconds.
In boxing, showboating often takes the form of taunting, dropping one's gloves and daring an opponent to throw a punch, or engaging in other risky behaviors while the match is ongoing. Notable boxers well known for their showboating style include Muhammad Ali, Sugar Ray Leonard, Roy Jones Jr. and Floyd Mayweather Jr.
