kibber
 n.— «As thousands of singers converge on Nashville for an international convention of barbershop harmony music, the old-fashioned music style is facing discord among its fans.…The signature sound of four unaccompanied male voices singing in harmony has been the roots of the style, but modernizers want new blood and fresh ideas. Supporters of the traditional style are also known as “kibbers,” for the slogan “Keep It Barbershop.”» —“Barbershop faces a discord among members” in Nashville, Tennessee Associated Press July 4, 2008.
