Wood chucking has nothing to do with what most people consider wood. Wood chucking is the well-known practice, used by average and bad sales representatives or lead generators, of submitting weak or outright false sales to management in a pathetic attempt to inflate their key metrics.
Wood, in this context, is the
fake sale. Chucking is the act of submitting a
fake sale, and a woodchucker is a no-talent assclown who
will be fired the first moment I catch his sorry ass chucking wood.
