well, I am surely getting to an age that many consider old - but there are a many terms I have found abrasive for a lot of years.
'my bad' - every time I hear it I think of some thickhead - hopefully this obnoxious saying won't last.
A couple of others that have lasted are ------------ 'enjoy' -- particularly when said by some idiot who has just delivered food to your table that inevitably turns out to be complete crap.
there are a whole heap of sayings that have infiltrated our language from the hell on earth called Hollywood -------
'Hi' is one ---- fully accepted now -------- but a poor replacement for G'day or hello.
'Have a nice day' - is also irksome - although I use something similar myself -- I realise it really should have stayed in America - complete with gum chewing and spitting tobacco.
'No problem' is a beauty -------- god knows where it came from - but it is almost a guarantee that you will indeed have more problems than you can poke a stick at. Ditto for 'no worries'.
Have you noticed that the same people that say 'no problem' or 'no worries' also say 'not bad' ---------- as opposed to good when asked "how are you?" or 'how is your day going?"
Basically if I walk in somewhere now and I ask someone how they are - and they answer "not bad" and I ask if something can be done and they answer "no problem" ------- I walk out
You can be almost 100% sure the good or service will stuff up.
Language is the pointer of the soul and the personality.
How often have you ever heard a truly positive upbeat person use the term 'not bad' -------- interesting, isn't it?
And the biggest load of crap of all ----------- corporate and political speak - my god, what a bunch of wankers.
