when you call something witty, you're describing it as clever or intelligent, literally, "this is [something] which is clever" but when you call something quippy, what you're saying is, "this is [something] which is [something] that is witty"
do you guys understand why it doesn't work now?
and just for future reference tadao, you shouldn't consider merriam-webster as the authority on proper usage, seeing as how they recognize"w00t!" and "fanboy" to be actual words aswell. the oxford english would be a far better resource. and just for amusement purposes, i did check it there and it doesn't exist.
