How it's used
This term uses the imagery of a duck living in a drainage ditch to imply someone is low-status, lazy, or generally incompetent. It carries a strong sense of contempt and is used to insult someone who contributes nothing to a group or situation. It is much more specific and derogatory than simply calling someone lazy.
