A soul patch (also known as a mouche, a flavour saver, or a jazz dot) is a single small patch of facial hair just below the lower lip and above the chin.
It came to prominence in the 1950s and 1960s, when it was a style of facial hair common among African-American men, most notably jazzmen. It became popular with beatniks, artists, and those who frequented the jazz scene and moved in literary and artistic circles. Jazz flute players who disliked the feel of the flute mouthpiece on a freshly shaven lower lip often sported the look. On the other hand, jazz trumpeters preferred the goatee for the comfort it provided when using a trumpet mouthpiece.
