Not so much the definition as the usage notes "In contemporary Norwegian, this usage is hardly known, and the modern definition is wank (masturbate)." These aren't usage notes, it's another definition. An IP just changed them, and since I don't speak any Norwegian I can't help, other than blindly assume that it does indeed mean (vulgar) to masturbate. Mglovesfun (talk) 23:48, 22 April 2011 (UTC)
The contributor tried to say that the original meaning of the word is "to sway", but it is now used chiefly in the sense "to wank". Thus your conclusion of "wank" being another definition was correct. The usage is exactly the same as in Swedish. Edited accordingly and detagged. --Hekaheka (talk) 20:36, 31 March 2012 (UTC)
