Old School

Old School Arm Fold: If you aspired to be part of the exciting new world of "rap" in the 1980s, it was unquestionably imperative that you fully mastered the Old School Arm Fold, depicted here by one of its most skilled practitioners, D.M.C. (of Run-D.M.C.). As poses go, it's ... moretrickier than it looks. You must fold the arms way up high, running the risk of scratching your arms on your enormous gold brocade pendants, and affect a facial expression of being mildly vexed. Perhaps best known among mainstream music fans, this pose was assumed in the "Walk This Way" video in response to those noisy guys from Aerosmith rehearsing on the other side of a paper wall.
