Fanfiction written by an author going by the name of "Oscar". Characterized by horrible spelling and grammar, as well as "Oscarisms".
Oscar was the first and hopefully only fanfiction author to write a Sailor Moon SI lemon involving Artemis (a cat) and Oscar (the self-insertion character, a hermaphrodite).
It's especially wrong when you consider that Oscar's fanfiction was written when "he" (Oscar claimed to be a hermaphrodite in real life) was 13.
Several of Oscar's fanfics were MSTed by Megane 6.7.
I read them and am permanently scarred.
