slang and colloq. [Of uncertain origin.
First recorded, as printers slang, in 1888; current among soldiers in the war of 191418, and hence in general colloquial use. There is no evidence of any connection with the northerly dialect word WANGLE v.1 Probably, like many other slang words, it was formed involuntarily, under the influence of an obscure sense of phonetic symbolism; the suggestion may have come from WAGGLE v.]
