Yep, a new one I'm hearing from some of the younger crowd. "Strad". Like others from different era's like; cool, neat-o, rad, boss, the bomb, groovy, bad, doozy, stud, tight, dope, and a host of others. This one, "Strad", is closest to "doozy", referring to the Dusenberg automobile, which everyone knows was indeed a "doozy". "Strad", referring to the violin, is likewise "the bomb"....because not one of the aforementioned "younger crowd" knew what a stradivarius was ;-}
