The problem isn’t that its not definitionally a meme but that people are jumping the gun on calling anything they post a “meme”.

If you post an animation and call it a “meme” you are being presumptuous that it’ll spread sufficiently to be considered memetic in the first place. Its like saying “You will all share this animation.” in the title.

Usually, people don’t title their image macros “meme” though they may later refer to them as memes if they have successfully spread/are shared.
