sideburns (SYDE-burnz) plural noun
Hair grown on the sides of a man's face, when worn with an unbearded chin.
[After Ambrose Everett Burnside (1824-1881), who served as a general in the
Union Army in the American Civil War, and who earned more recognition for his
side whiskers than for his military career. Eventually the term burnsides
morphed into sideburns as such a facial pattern was on the sides of a face.]
