Well, nothing in cinema is really 'unique' anymore is it, I don't think it was meant to be taken literally, and I did say '...in the 90's'. I'm aware there were plenty such films prior to Tarantino, particularly in the the 70's, but I feel they fell out of favour in the high-concept 80's (MDWA being the exception that proves the rule
In that case, I agree with you. My dislike for Tarantino's signature began during that period because almost every spec script we saw had insanely long dialogue chunks with oh-oh-ironic pop references. The trend returned to life after every Tarantino (and in fairness, Roger Avary) release during mid-1990s and early 2000s. Naturally, this gave some a few hours' worth of heavy drinking and bitching bitterly about copycats, especially those who did it badly. The others tell me it still happens and that it's now known as the Tarantino Effect.
