Imus and his staff couldn't figure out what the hell he was talking about and thought Rather had said something about tampons.
(Rather came on later to "explain" that he came from a long line of ditch diggers and this was a common expression among them like "take care of yourself".)
Unfortunately, more often than not, in his innate ignorance and sorry fashion sense, Rather chooses these obscure phrases to hopefully convince the listener that he is a wise and brillant man who once stood down Hurricane Carla on the Galveston Seawall and wore a lime green safari suit with matching shoulder holstered .38 cal pistol as he filed reports from his Saigon hotel bar corner sandbagged cocktail table to Uncle Walter who no doubt encouraged the halfwit to pursue this method of slanted reportage.
