It all depends who is describing it. Small animal, big eyes, sharp teeth and mean, many other variations. The idea is you get some sap and talk all day about hunting them that night. When night comes you tell him he will have the honor of holding the bag while everyone else drives the critters into the bag. He is cautioned not to let any escape because they are worth money and you are going to divide up the nights take. You take the guy out into the woods far from camp and tell him to stant there while you drive the critters to him and he will have to open the bag and let them run in to hide from the drivers. Everyone then goes into the woods yelling and eventually the yells stop and everyone is gone back to camp. Leting the guy standing in the middle of the woods in the dark,"holding the bag".
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
