When one tries to be suave and quote a movie line, and then can not remember which movie the quote came from - and ends up looking like a dumb-ass.
Super hot chick you're trying to impress: "Ok, so see you later then"
You (fumbling for something cool to say): "Don't worry, We'll always have Paris"
Super Hot Chick: "Um, is that from a movie or something"
You: "I can't remember!"
Super Hot Chick: "You just had a Casa-Blank-Out, dumb ass!"
