flipper
n.— «Playing hockey is a decent alternative to flipping through an endless conveyance of steel bars, culling out the bent and twisted pieces, careful that the razor sharp ends don’t slice through protective gloves. In mill parlance, Thornton that summer was a “flipper,” hired to eyeball defective steel rods and yank them for disposal.» —“Planted seeds of hard work” by Kevin Paul Dupont Boston Globe (Massachusetts) Ju;y 20, 2008.
