tokunbo
adj.— «If any part or bolt or nut shows any sign of working less than 100 per cent, it is automatically replaced with a brand new one, a practice which is in sharp contrast to the tendency to use a “tokunbo” (second-hand) item vandalised from a disused or parked equipment to replace the defective item.» —“Airlines and Air Safety” by Oscar Ikwuemesi This Day June 26, 2002.
