whoop de doo
n.— «On the second day, we encountered 29 km of whoop-de-doos. For those unfamiliar with dirt bike vernacular, picture the harshest mogul run you’ve ever seen, lay it out horizontally, throw in some sand and you have whoops. It was amazingly invigorating. Whoops are best approached standing up, with you legs pumping like shock absorbers. Normally after a few hundred metres of this pounding, your legs turn to Jell-O.» —“A dirt biker’s dream 200 km of scrub, rocks and whoop-de-doos can hardly be called a ‘tour’ but Baja was a blast” by David Booth Toronto Star (Canada) June 1, 1996.
