Origin and Etymology
When folks ask what does loon mean they usually want both the slang and the origin, so let us start there. The English surname and word goes back centuries, and it overlaps with ideas of madness that come from Latin luna for moon, which fed the word lunatic.
The animal called the loon is a water bird known for eerie calls and awkward landings. That bird imagery nudged the word into describing odd behavior. For a formal source, Merriam-Webster traces the slang sense to that same cluster of meanings, and the bird page on Wikipedia helps explain the natural imagery people were borrowing.
