whoop
n.— «The track, part of the North Hudson County Park, snakes downhill along 800 feet of brown dirt. It has, to use BMX jargon, three ‘‘berms’’ (banked curves) and five ‘‘whoops’’ (bumps). One of the whoops is a ‘‘table top,’’ a bumb that is a bit flat on top.» —“Young Daredevils Flocking To Bicycle Tracks” by Philip Senon in North Bergen, New Jersey New York Times July 4, 1983.
