The red-haired kid was a kid who founded the No Homers society in his treehouse.
When Homer wanted to enter the treehouse club, the kid said that they were no Homers allowed, and then Homer points out that they let in Homer Glumplich. It was then explained that there couldn't be more than one Homer in the club because it was a No-Homers Club.
