We have a friend who says 'Oh bad words, bad words, bad words, bad words*
It's strangely satisfying!
I do like 'Seriously' and 'Oh really' and the idea that you can put as much meaning as you like into the intonation without actually saying anything degrading.
Once upon a time, on a Scout camp aboard a canal boat, some delightful leader crashed into a bridge whilst I was getting toast out from under the grill ... Four little scouts poked their head around the door and said "Helen ... you just swore" and the the fifth little darling came in and said "Umm, I smell bacon" .... I used more expletives than I actually realised that I knew in that ten minutes! (and I still have the scar on my wrist today)
Here, at home with 6 and 3 year old boys, we seem to have fallen into using 'BAD CAT' ... this is probably because most of our swear worthy moments invove a cat in the wrong place at the wrong time!
We were supposed to used 'Drat' 'Blast' or 'Rats' as we were growing up ... though I confess I used'Bloody' more that I ought to, as historically it's a curse on the Virgin Mary (By Our Lady) ...
