I suppose the proper hackish definition is basically "a bug," but it's also an online fan fiction/fanfic epic that includes elements of anime such as Dirty Pair and other geeky topics. Full of angst and geek humor, it's probably the only anime-related fanfic worth reading. It's by the Eyrie Productions group, who also do Neon Exodus Evangelion, loosely based on the Evangelion anime. www.eyrie.net
