You are a Billy Buttercup!

[MW]

What are you?

Origin?

MW,

This is a regional expression, probably originally based on a character in a book or movie. In order to know what a "Billy Buttercup" is, you would have to have seen the movie or read the book. Just looking at the name (without know for sure), I would assume it is an insult.
