My father (a strict grammarian) had a field day whenever that schoolfriend came to visit my house. He would pick on every error, and there were a lot of them! She was one of those children who couldn't/wouldn't pronounce "th" at the end of a word properly so she said "wiv" (with) and "boaf" (both). As I said, she used "brung/brang". She had very long hair which was frequently in two plaits, tied at the bottom with bright red ribbons. Unfortunately, she insisted on pronouncing it "ribbin".
On hearing each error, my father would say something like "Brung? Brung?! Where was you drug up?"
In case of confusion, his words were purposely ungrammatical to emphasise the fact that the listener/my friend had not used English correctly. The correct version would of course be "Where were you dragged/brought up?" The use of "to drag up" is a sort of pun on "to bring up". His suggestion was that the person could not have been brought up properly, resulting in their inability to speak English properly, therefore they must have been dragged up.
