Agreed. I went on a course 5 years ago where one of the presenters was a detective sergeant. He counted a conversation he overheard between two co-workers on a train to work one morning, then showed how he could use this seemingly trivial information to get past building security with an important private message for one of them...So, you were born on the first of August 1963, then?
Interesting. It also meant that you did it by hand, which was old fashioned! That may be how it came to derogatory connotations? Rather than the precision of a machine engineered product, something put together by a person, with no standardisation of sizes, just to fit?
Usually when someone says something is a “bit of a bodge” nowadays, they mean it was cobbled together and is a bit rough ready. Which is a slur on shoe repairers (not shoemakers, they were different). And me from a shoemaking town.
“Me, I’m Just an average bodger,” is often used either as a form of humble bragging, or as a way of saying, “I could do better, but didn’t try”, which is why I dislike it - who wants to aim for mediocrity?
(As an example, I would never have made it as even a 10th tier football player, and average would have been an improvement, but I always wanted to be better than that!)
