Inappropriate Nickname

Would anyone ever call a millenia-old, extremely wise, competent and quite-likely-to-be-deadly-if-you cross-him Elf 'Leggy'? You'd think not. You'd think 'that's just not right'. But people do. 'Leggy' is just one of a whole host of inappropriate nicknames; embarassingly fubsy diminuitives given to canon characters by their rabid fangirls.

Using an Inappropriate Nickname is a charge. In some cases, INs become minis; in the Good Omens Official Fanfiction Summer School, they become mini-Hellpupppies; cute and fubsy and even more rabidly insane versions of mini-Hellhounds.
