"Memetics deals with information transfer, specifically cultural information in society. The basic idea is to conflate the exchange of information between people with genetic material, to track the mutation of ideas as they are transmitted from one person to the next in the way you could track viral transmissions and mutations. However, a meme also provides benefits to the carrier if they spread it.
Understanding the true nature of memetic threats is critical to surviving them. You cannot wear a special set of magical goggles made of telekill to protect yourself from a meme. THE GOGGLES DO NOTHING. If you just read those words in your head with a bad Teutonic accent, congratulations on being victim to yet another memetic effect. If you did not know that phrase was an oft-repeated quote from the Simpsons then congratulations; you are now infected with that knowledge and are free to participate in its spread.
A meme perpetuates itself by being beneficial to the carrier to spread to new hosts. You now understand that THE GOGGLES DO NOTHING; you’re in on the joke. However, you might have friends who aren’t, and don’t get it. It benefits you to explain them, because then you both have something new to laugh together about when it gets brought up. This is what makes a meme effective - how much incentive a carrier has to spread it. Unless an anomalous meme’s effect is the compulsive urge for the carrier to infect others, there needs to be incentive to spread it."

“An antimeme is an idea with self-censoring properties; an idea which, by its intrinsic nature, discourages or prevents people from spreading it.
Antimemes are real. Think of any piece of information which you wouldn’t share with anybody, like passwords, taboos and dirty secrets. Or any piece of information which would be difficult to share even if you tried: complex equations, very boring passages of text, large blocks of random numbers, and dreams…” -SCP Foundation Antiemetics division
