bullica 10
1st_ Stage name (I owe them the real one) of a Brazilian electronic house musician. Although Cayetano Peláez del Rosal's definition does not appear in the dictionary of the RAE, it occurs to me that if it were an Americanism it could come from bolas ("common currency") or bola ("large quantity"), although it sounds more like noise to me because of the shouting of children. See suffix -ico .
