That's it. You let the meme fester in your mind. Slowly, the more you think about it the funnier it gets. Coincidentally you'll also have a much more difficult time preforming, communicating with others and reading. You will think about it more and it'll get funnier. You will notice a punk slime dripping out of your ears and nose accompanied by a rotting smell emanating from your skull along with flies buzzing around your head. It will be at this point when you'll truly understand and appreciate memes like this.
In Internet culture, shitposting or trashposting is the act of using an online forum or social media page to post content that is of "aggressively, ironically, and trollishly poor quality". Shitposts are generally intentionally designed to derail discussions or cause the biggest reaction with the least effort.
