Imagine yourself putting on a Yorkshire accent for these quotes from the 19th century. If you are actually from Yorkshire, then this should be a doddle.

"Ah wadn't cag-mag aboot wiv 'im, if Ah was thoo; he's neeah sooart of a mak for thoo."

"He gav up his awn thrade an noo gans cag-maggin aboot cunthry like neeabody."

Cag-mag was tough old meat that was just about off. Then the term was applied to anything valueless or worthless. Then it got used for people, especially disreputable old ladies. Sadly, it then got applied to what were then called 'simpletons'.

"D'ye think Ah wad be seen wiv an awd cag-mag like that?"

"Yo cagmag, yo."

"He's only a poor cag-mag of a fellow."
