gravy plane
n.— «As Fife and Warren pour out details and examples-the GST exemptions, the “gravy plane” junkets, “double-dipping” through piling patronage jobs on top of generous pensions-you really do lose your faith in parliamentary democracy.» —“Bliss On Books Leaders And Lepers” by Michael Bliss Globe and Mail (Toronto, Canada) Oct. 18, 1991.
