I gather from Cormry Novel & Stormlight that nobles are likely as not to call war wizards things like “drunken louts” or “voyeuristic nuisance” [paraphrasing] & Purple Dragons have “happy dancing mages” if memory serves.
Do the Blue Dragons have any names for ‘em? Sure. "Vangey's hounds" (sometimes with "panting" or "baying" or "non-housebroken" added). "Lubberspells" (because they sometimes hurl magic w/o thought for effects on a ship), Also "idiot figureheads." ;}
BTW, all non-nobles in Cormyr call nobles "highnoses." ;}
