Black Market Meme 

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.

Guy 1: *sends a meme going from buzz lightyear taking off to 9/11*
Guy 2: Bro that's messed up, where do you get these Black Market Memes?
Guy 1: I have a top secret source, I don't wanna get in trouble for them.
