Soldiers, forest rangers, fisherman, and other workers who get paid in one lump sum after a long season of work become "cowboy rich" on payday. Usually connotes blowing all the money on a whoop-it-up session in town.
Those mean bastards from the Bar K ranch will be cowboy rich on Tuesday, but they'll drink all the money by Saturday night, shore 'nuff.
