I had a boyfriend years ago, who was not around very long, thank goodness. The irritating things he did and said were many, but one that sticks in my mind was that at the end of a great number of our conversations was this phrase "Never mind, it'll all come out in the wash" - which means, I suppose, that whatever the problem is, it will eventually resolve itself. At the time, it seemed such an inane comment to me, because he applied it to everything, and it came to be meaningless. It also effectively meant the end of whatever discussion we were having. Drove me nuts!

There were a few expressions used in my family which I have not heard anywhere else - My grandfather, who did not like swearing, made up an exclamation of his own that he could use - "Great Everlasting Hambone!" I don't say it though. My dad used to say "Every horse to his own nosebag, said the old man as he kissed his cow", which has the same meaning as "To each his own", and I do sometimes like to use that one. I have not yet met anyone who has heard it before, so I do get some funny looks ;-)
