When I was a tween (or almost) someone developed a beef with a local sysop and started posting, "WE HAD A DEAL!!!!!!!!!!!!!!" over and over on the BBS's graffiti wall that you saw at login. It became a local meme and people started posting it everywhere in the local calling zone for no particular reason. It was the first sort of flash event I saw, and a significant development in the local culture I was in, but today that culture has been entirely destroyed, and it's a weird thing I don't share with anyone. But it always comes to mind as though it might be relevant, and never is.
