Excessive management-speak, especially 'thinking outside the box' and 'incentivizing' and 'impact' as a verb.
'New normal'; it's not normal!
''Unprecedented': not for me. Some of us had long-term health problems in our youth, and this is like a return to them. Some always had health problems! And of course before modern medicine, this is what any infectious illness was like, and without the technology!
'I don't want to be rude, but...' Usually means that they do want to be rude!
'I'm not racist, but...' Ditto!
'Shitty'. I don't mind swearing in general, but really dislike this word,
'Happy birthday' if said to me. I can't bear to be reminded of my birthday. And no, it's not today (might be better if it were; better chance of it being forgotten in the run--up to Christmas!),
'Toughen up' or its more modern equivalent 'you/they need to learn more resilience'. Not saying that it's bad to be tough or resilient; just that these expressions are often used as an excuse to blame the victim of bullying.
