"eternal september" refers to when the internet became accessible to "normies," thus supplanting the old internet vibe (mainly hackers, engineers, etc) in favor of being useable by the general public.
Someone who went online for the first time in September, when college starts and students get a turnkey way to do that, as opposed to gaining the interest and working through the process themselves.
