The title of this thread should really be "FFXIV Image Macros" rather than Memes.

While we have many, many pages with many, many image macros, I am not sure that many of them can be considered 'Memes' instead of just funny pictures. There are some topics that I would consider memes such as the FFXIV forum reaction to ARR Grass, coining of the phrase "Derplander" and Thancredites vs the rest of the FFXIV forum-ers.
