Do you not consider this a meme? If I may ask, why not?

Frankly, I have trouble defining what a 'meme' really is. Traditionally, a meme is an idea of some sort that spreads through a culture. A more modern definition would be:

An amusing or interesting item (such as a captioned picture or video) or genre of items that is spread widely online especially through social media

So personally I would say this post a meme and thus belongs here. However, I don't know if Webster's definition is really what posters here, and more importantly the mods here, would use.
