Cancer

"This thread gave me cancer."

"______ is the cancer that's killing /tg/."

From the Greek noun 'karkinos' which meant both the hard-shelled crustaceans you find on the beach, and the hard cysts ("cankers") you find under your skin when you're infected with a plague. When the term is used on 4chan, it means a meme that the speaker fears will kill the host organism (ie. anyone who looks at it), and likely infect others to kill them as well, "degrading" a board and its community as a whole.

Just about anything can be called "an cancer," because butthurt fa/tg/uys will use extreme reactions as a first resort. Some ideas seem to attract this label more than others. Here's a short list:

• My Little Pony (supporting or hating it; /tg/ just wants to get on with its fucking life)
  • Any and all obsessive fandoms, to a similar extent.
• Cultist-chan
• F.A.T.A.L. in general (though extracting humor from it is well and good)
• Lengthy, marathon discussions about Matthew Ward, when everyone already knows how much he sucks, and why, and /tg/ just wishes it (and GW) could move on...
• The fights that break out when someone compares 4E to other editions of Dungeons & Dragons
• "Stat me" threads
• "This is how I X" threads
• Quest threads
• Skub vs. Anti-Skub discussions by idiots who don't understand the meme involved
• that fucking game.
• New memes, old memes, red memes, blue memes
• /b/, and /b/-related anything
• /pol/ and /pol/-related anything
• LWDM
• Yaldabaoth

And to a Lesser Extent

• Anything you hate about any site you are on, from your perspective
• Anything you like about any site you are on, from someone else's perspective

In Conclusion

/tg/ is the cancer killing /tg/.
