While some might argue that memes have gotten “weirder” over the years, if you take a trip back in time and go through the internet of the '90s and early 2000s, you’ll find that things were already a tad strange, unusual, and niche. Dancing animals, the often incomprehensible-to-outsiders rage comics, and inside jokes on top of inside jokes. 

The truth is, the speed and ease of use the internet brings allows basically every community with a common language (or even concepts) to create and share memes among itself. This is why every demographic, fandom, and profession has a meme page just for it.
