grime
n.— «Grime is, however, seriously rowdy, rave-reared party music and has already yielded some of the freshest and most exciting young MCs to be heard in years, making it the perfect antidote to North American hip hop’s continued creative stagnation.» —“In Rotation: Grime primer” by Ben Rayner Toronto Star (Can.)
