catchphrases are not memes, asshat
memes are jokes that repeat themselves with little modifications each time
catchphrases/quotes are just the mentioned.
now if the humor is similar to the ones in macros, or in popular stupid jokes, that does not mean a thing, or else you are calling every single act of immature/random jokes as "memes"
nowadays people call movies memes, just as actors or games. in short everything is being called a meme since it sounds like a offensive buzzword
