My favorite nickname, besides the fools who've been completely omitted, is "Lord Too Fat to Sit a Horse." Perhaps b/c he's one of my favorite third tier characters. The Northern Lords are really all given their own personalities, even those who hardly appear on the page. Greatjon Umber and his brothers plus SmallJon, the Leech Lord and the Bastard, Rickard Karstark, the Reeds, Lady Mormont and her daughters, Lady Hornwood, Lady Dustin. They're all interesting.
