eternal september

Refers to the fall of 1994, when AOL let the great unwashed onto Usenet for the first time. Prior to 1994 Usenet experienced annual suckage in September when new college kids got Internet access for the first time and broke things. After the dawn of AOL-Usenet interconnectivity the suckage didn't stop until 2005 when AOL revoked Usenet access from its members. Now refers to any situation in which new users flood a community and destroy it.

Q: "Dude, what's up with all these noobs asking dumb questions on Usenet?"
A: "Eternal september, man"
