whippy
n.— «A chief of detectives at Kings Cross, Detective Inspector Brian Meredith, had said he was against police taking regular bribes but as far as he was concerned they could pocket “whippy”—money they found on searches—the Police Royal Commission heard yesterday.…“He said to me he was against anyone accepting a “retainer,” as he put it, but if you went somewhere and found a “whippy,” then as far as he was concerned, it was a free-for-all,” Sergeant Scullion said.» —“‘Whippy’: Not A Bribe, Just Money” by Malcolm Brown Sydney Morning Herald (Australia) July 11, 1995.
