I heard someone use the term ‘swamp duck’ today. I’d never heard it so I looked it up. Apparently it has several unrelated meanings. Some being:
~Often used by teachers, this term is widely used and will often make you cringe. (Sam please take your hat and headphones off my little swamp duck")
~It refers to a person that can do so many things, but master of nothing. (jack of all trades)
~A snitch, a liar, a conniver.
Among other things. I even read it can be a term of endearment! But in my 60 + years on this planet, that was the first time I’ve heard it.
Where did you look this up? Because some sites, like Urban Dictionary, let just about anyone add whatever they want without needing cites or any sort of reference.
Never heard the term before. If I had to guess without context, I’d have through it referred to a double-crested cormorant. They’re common in Florida swamps and rivers.
Finger Lakes New York, have been elsewhere in USA, never heard it. I would have assumed somebody was talking about a kind of duck that likes swamps; though that probably includes quite a few ducks.
