Britpick

To Britpick, verb. The act of noting and complaining about any and all instances of non-English English, in particular the so-called "American English". Britpicking Agents deny this dialect the status of a true language, and are wilfully confused by it. Occasionally, they are also overwhelmed by it; overly American fics have been known to cause stress, headaches, stomach upsets and violent rages.
