My 14 year old daughter has started saying "true", to absolutely everything. It's driving me nuts, I know we moved to Oz 2 years ago, but cut that crap out, even Ozzies don't say it!
I also get annoyed when people cant pronounce her name correctly, ok it's Irish Gaelic and only been around for about a thousand years, but f.f.s, it's Eilidh; pronounced Hayley but without the 'H'.
How feckin difficult is that!!!!
Oh, and my wife also say's "yadda yadda yadda" when she is abbreviating a story, that frakkin annoys me too.
