Not another one.
Oh, did I spell it wrong? :-[
Spelt it Mackem. Geordie spelling is "howay". It's actually derived from "half-way" (something they used to shout down the mines) though so the Mackem way is more 'right' I suppose (although both spellings are phonetic anyway/to do with the accent). Gemmill told me this. Doubting him, I looked it up and he's right. I hope I didn't bore you too much there.
So what about, "heware" ? Becuase i don't say, ha'way
