Etymology of the verb 'to mimse' and derivatives - Lud
I am reminded by the thread on motoring writers that a little while back I communicated with the editorial desk of Motor Sport to try to investigate the etymology of 'mimser' and its variant forms, which as far as I know was first used to mean a slow, unaware, obstructive driver by William Boddy and DSJ of that magazine. That anyway is where I first saw it.

Mr Boddy is now in his nineties, so I didn't want to harass him. But I got a courteous reply from Gordon Cruikshank, the deputy editor, saying he had mentioned the subject to WB. Rather disappointingly he couldn't remember exactly how the term had originated, but thought the Lewis Carroll poem Jabberwocky might have something to do with it. Someone here suggested the same thing in a previous thread.

One wonders what backroomers can come up with when drivers gyre and gimble ... IN THE FAST LANE.

I certainly mentioned a link with the Lewis Carroll poem - maybe others did also. He might have derived the word from older British dialects where it was used in describing anything overly refined, mincing or affected.
Whatever the final answer, 'mimse', mimsy' or 'mimser' all seem to point to a rather mincy prissy affected quality or behaviour - well suited to Lud's (derived) derivation from the old motoring writer mentioned - probably an LC fan & studier old English dialect himself no doubt.

You may well be right woodbines. My ex-wife, neither a motorist nor especially literary, used to use the expression 'mimsy' to mean wimpishly affected and feeble. She had probably learned it from an adult as a child rather than invented it herself.

The OED still has only the adjective (unless it is one of the 2000 words recently added):

?Prim, prudish; contemptible? (E.D.D.).
Lewis Carroll's mimsy, which may be an invented word, has influenced all subsequent uses.
