A handlebar moustache is a moustache with particularly lengthy and upwardly curved extremities; a shorter version is named the petit handlebar. These moustache styles are named for their resemblance to the handlebars of a bicycle. It is also known as a spaghetti moustache, because of its stereotypical association with Italian men. The Handlebar Club humorously describes the style as "a hirsute appendage of the upper lip and with graspable extremities".
Similar styles of moustache are quite ancient, appearing on statues and other depictions of Iron Age Celts. In the United States, handlebar moustaches were worn in the later part of the 19th century by Wild West figures like Wyatt Earp. In Europe, handlebar moustaches were often worn by soldiers during the 19th century through roughly the World War I era.
In 1972, to win a $300 "best facial hair" prize offered by team owner Charlie O. Finley, Oakland A's pitcher Rollie Fingers grew a handlebar moustache which he sported throughout his career.
More recently, the contemporary hipster subculture has embraced the handlebar moustache by mocking conventional ideals of fashion, and by ironically combining a highly manicured handlebar moustache with the portrayal of an unkempt appearance or a haphazardly selected clothing ensemble.
