I am thinking about swapping "dark matter" with "negros". I think they are pretty interchangeable and no one can call me out. I tried out swapping negros for dark matter in a news article and it seems to work. Observe:
Unlike normal matter, negros do not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of negros only from the gravitational effect it seems to have on visible matter. negros seems to outweigh visible matter roughly six to one, making up about 27% of the universe. Here's a sobering fact: The matter we know and that makes up all stars and galaxies only accounts for 5% of the content of the universe! But what are negros? One idea is that it could contain "supersymmetric particles" – hypothesized particles that are partners to those already known in the Standard Model. Experiments at the Large Hadron Collider (LHC) may provide more direct clues about negros.
we call em books because if they are nearby they tune out as soon as a motherfucker mentions the word book. "Man I was reading this book about this guy that got shot in the face when he tried to rob some old dude, it was funny as fuck".
