lapper
n.— «Cold comfort as it may be, hooning is not an exclusively Brisbane problem. In Hobart, hoons do what is called “block bombing” where they roar around the CBD block. In Ipswich, hoons are called “lappers.”» —“Academic interest in hoons” by Christopher Bantick Courier Mail (Brisbane, Australia) Aug. 28, 2007. (source: Double-Tongued Dictionary)
