Goatse
From Jenny Everywhere Wiki
“Goatse” was the name of an extremely offensive meme which existed in some universes. One version of Jenny Everywhere believed that the sandy-haired man had invented a meme even more offensive than “goatse”, justifying the summoning of herself and many other Jennies to his universe to cow him into apologising. This was, however, only one of many guesses. (PROSE: Paying It Forward)
