There are quite a few examples of idioms, phrases, or even single words, specially coined for a movie scene or a television sitcom. When adolescents hear these new expressions and find them interesting, they incorporate them into their vocabulary. That tends to be short-lived, though. Here are a few examples:
"Check out the big brain on Brett!" If you saw "Pulp Fiction", the movie, you probably remember the scene when Jules and Vincent ask Brett "what do they call a Quarter Pounder with cheese in France?".
Fred Flintstone's "Ya-ba da-ba doo"
Monty Python's "upper-class twit"
They are not exactly slang phrases. Is there a word or phrase for these temporary acquisitions?
