floss
 v.— «The scene metamorphosed into “kind of a floss-fest,” notes R. J. de Vera, a tuner pioneer who oversees his own performance-oriented brands RO— JA and Motegi Racing. “Flossing” is a hip-hop term that means showing off, a big part of the sensibility that shaped the “dub” market.» —“Hot Wheels” by Rob Walker New York Times July 11, 2004.
