Get on with what you’re doing or quit and give someone else a chance; stop putting it off. This metaphor, alluding to a fisherman who ties up the use of a boat or rod when he could at least be preparing bait for others to use, originated in nineteenth-century politics. It appeared in the Congressional Record in 1876, when Congressman Joseph P. Cannon, telling the Democrats to vote on a bill that would legalize the silver dollar, said, “I want you gentlemen on the other side of the House to ‘fish or cut bait.’” A ruder twentieth-century American version is shit or get off the pot.
