“You’re joking, Weasley!” said Malfoy, behind them. “You’re not telling me someone’s asked that to the ball? Not the long-molared Mudblood?” (Harry Potter 4 [US Version]: p.404)[Bold font is mine]
N.B.: Malfoy, who hates Hermione very much, is insulting her. In the past, he hexed her front teeth into long, beaver-like teeth. However, her teeth are normal now. Mudblood is an insulting word in the magical world.
I know a molar is any of the large teeth at the back of the mouth. So I can’t understand why he refers to back teeth after his hex to her front teeth.
Does ‘long-molared’ have special meaning? Or does he say so on purpose in order to express his indifference to Hermione?
