n. usually a referance of insult towards a person who is very simple. A person who does things, or behaves in such a way that others would think them very immature or ridiculous. This term is used because it is assumed that a green moth is one of the most simple and unintelligent creatures.
1)Aaron is such a green moth, poor guy.

2)What are you? A green moth? Friggin idiot.
