Litterbox effect

When a very large number of people hold onto a completely ridiculous and bogus belief, no matter how extensively it is disproven, to push an agenda, while often even knowing deep down that it is inherently untrue.

Examples of the litterbox effect include:
- Schools supposedly placing litterboxes in bathrooms for furry students (the namesake of the effect)
- Anti-vaccine sentiment
- Climate change denial

Letterbox

When u beat ur knob head with a tenderiser untill its flat, u lay on ur side and penetrate ur mrs so it looks like ur delivering a letter. U must shout "Postman Pat has delivered" as u climax for added effect. Bonus points if its an interracial threesome as it will create the illusion that jess the cat is there with u

"Ayo u wanna letterbox tonight?"
