Knights Who Say 'Ni' Effect
When something good (or at the very least "okay") becomes insufferable by association with those who like and/or praise it.

In the time since then and the release of Portal 2, you'll be pleased to hear that I eventually did come up with a criticism for Portal 1: it's got the worst fucking fans in the world. Nothing ruins a good thing quite like knowing you share your opinions with mindless little tits who bray like mules if you so much as mention the word "cake," and the good thing in question can never be the same again. This is technically known as the "Knights Who Say 'Ni' Effect."

All the dumb motherfuckers of the internet world think they are gay when they say it all the time. I say fuck them, and shut the fuck up you stupid bitches.

John says, "im 1337 noob"
Rob pulls out his penis and begins to pummel John with his cock in the best Danza slap ever, and says, "Shut the fuck up you stupid bitch, people who say noob are fucking morons"
