Everyone wants what they don't have. You have speed, I have weed. You're nervous about having pills you stole from your brother, I ought to be nervous about having something illegal, but I'm not because I'm stoned.

A Black Market Meme are memesthat are from the very deep memiverse that can reach the top tiers of edginess. Typicals include 9/11 jokes, random jumps to violent porn, hitler, and more. These are very hard to come by, as posting them on social media sites often get you banned. Because of this, some have been transferred and shared so many times they become very low quality or even scratchy/distorted. These are the memes that will secretly last forever, slowly circling the world.
