flopper
n.— «Though racers refer to them as “floppers,” Mageau said, Funny Cars got their current name “way back in the ’60s. The first versions of highly modified cars were still steel bodies, but they moved the axles on the chassis to get a better weight distribution and they looked funny. People said, ‘Oh, that’s a funny car.’ And it stuck!”» —“Time is Funny” by Dave Cameron Edmonton Sun (Alberta, Canada) June 9, 2006. (source: Double-Tongued Dictionary)
