Not sure if anyone in the world knows precisely what is a internetmeme and what is not, I am wondering if the writing style "worst. thread. ever." is a meme.
Its origin seems to be the Comic Book Guy from The Simpsons (https://www.youtube.com/watch?v=Lzyd91NFx-Y ). It's a widespread stylistic tool on the interwebs for quite some time now, but alas, no funny pictures. A lot of copycat behaviour though and it does fit the Dawkins definition. So, why not?
