A bunch of Oxford researchers have compiled a list of the Top 10 Most Irritating Expressions in the English language:
10. "It's not rocket science" 9. "24/7" 8. "Shouldn't of" 7. "It's a nightmare" 6. "Absolutely" 5. "With all due respect" 4. "At this moment in time" 3. "I personally" 2. "Fairly unique" 1. "At the end of the day"

And can I please add a few?

“Perfect storm” "Do the math” "Keep me in the loop" "Awesome!!"
