Being from Darn saaf (I dont see how we see it like that to be honest) I would say the Geordie accent. Why my mum couldn't move to Newcastle rather than Dad down here still gets on my tits! Love the Polish accent and love a west country accent too. Really don;t like Brummie or Scouse though
Scouse - but only on a woman. French women speaking eenglish. Remember going to a conference when I was at university and hearing a female french scientist pronouncing n-hexane (hen-eggsane) and hydrocarbon (idrocarbon) and decided it was the life for me.
My Indonesian wife has a funny accent as well. When she says she wants me to make love to her it sounds just like "not tonight love I have a headache". We always laugh about it afterwards.
Jamaican although the obvious choice is quality. To be honest I like quite a few. Local ones like Ashington is brilliant when the old gadgies start rolling their "r's". My bro had an eastern European hottie clean his flat. The combination of her speaking English and being a hot maid was quite something
I lived two years in Liverpool and there is nowt worse than a scouse lass especially angry, the voice triples in volume, goes up umpteen octaves and shrieks, utterly horrible.
