athafnarmaðr

and athafna-, m. a busy enterprising man, Hkr. ii. 255, Fær. 209. In a bad sense, a laughing-stock; göra e-n at athafnarmanni, to make a butt of him, Sturl. i. 24, 181, this last sense seems to be peculiar to the first and second part (þáttr) of the Sturl., which were not written by Sturla himself, but by an unknown author.
