Green’s Dictionary of Slang

stangey n.2

[phr. ride the stang, ‘to be mounted astride of a pole borne on the shoulders of two men, and carried through the streets for the derision of the spectators’ (OED). This custom, however, once popular in Scotland and the north, focused on unpopular, rather than spec. wife-dominated men, but the implication is that he has to ride a pole, since he cannot ‘ride’ his wife]

a man who is dominated by his wife.
