A term used typically to describe someone as a testicle. If someone calls you a nard, immediately slap that bitch, because when someone calls you a nard, they are trying to post up as the cool kids say along with their dumb squad of fuckboy baked vegetable looking asses.
Bill Cosby: "YOU NARD!"
Jerry Sandusky: "C'mon..... I barely touched that kid man.... why you gotta hate bro??"
