@Sturgis,
There was a BBC documentary about the origins of words and phrases. People were asked to scour attics for oldest use of phrases like Pear Shaped.
Pear shaped never did get a satisfactory answer but Mackem did. Someone found an old football programme from 18 something or other with the phrase,
“We tack ‘em and we mack ‘em.”
Which for those of us not from Sunderland is we take them and we make them, reference to Sunderland’s industry.
