1. One who flings poop, particularly monkeys.

2. A person who reminds you of number one above.

3. Slang for someone whom you find obnoxious.

There can be a slight modification: "Hung-dung monkey" means the monkey with the big wang is a poop-flinger, for example.
That Mike can be a real pain in the ass. He's nothing but a dung monkey.
