Don't mind 'sorry for your loss' - or even referring to a dead person as having 'passed', better than 'x fell asleep'. No, dying and falling asleep are NOT THE SAME THING. Though 'a lady has passed' does almost ask for someone to add 'a gallstone' at the end...
Abbreviations, particularly cutesy ones, annoy me a lot. Hollibobs, sainsbobs, 'puter, mat leave (creme 'pat' is a particular abomination I hadn't come across before that has just made it into my top 10 - thanks mrsminiver!), jacket pot, tommy K... etc etc etc.
'Unpack' used in management-bollocks-speak to mean 'examine'.
And of course, 'empowering' when used in the sense of 'yes the feminists are going to get upset about it, so if we call it 'empowering' it's all right, isn't it?' No.
