Wow, talk about a blast from the past. That's something I haven't seen since early 4chan. Not sure if it's a good memory or not, but it's nostalgic anyway.
That image predates both Danbooru and EncyclopediaDramatica by a long while.
It was first popularized (as far as I know) on the first edition of 4chan, when there was a rule against posting Ayanami_Rei. She had been being spammed endlessly, and every blue-haired anime girl posted began to prompt cries of "zomg teh rei!"
Man, if only I can post things like these and not get a -20 record on my page from the mods and get IP Banned for 200 years in Danbooru, Tyranny sure is great.
Well at least we know what we can post for 葉月 to approve now! That's a win-win for me. Except just one question; How big should the cock be?
