knock
n.— «The knock among the craftsmen and contractor, fishermen and lawyer barflies I run with is that the Gravy Yard, as they call it, is a bit of a club. Someone can get you “in” as a maintenance or whatever grunt, then five years later getting paid on an underwater welder’s scale, even though the only time the guy puts on his wet suit is when he goes surfing.» —“The privatizing of the American military” by Chris Elliott Portsmouth Herald News (Del.)
