Spoffy, the 'she was like...' has been hanging around too long for my liking. I wish it would disappear, never to return.
I'm all for words being used 'properly', but not everyone agrees on what that is. I don't feel hide-bound by some old meanings - the 'shambles' one, say, or even the 'mayhem' mentioned in the OP. My 92-year-old father-in law and my 20-year-old neighbour both use the word 'wireless', for completely different things - and in context, there's no confusion about meanings.
