Some of the others are already mentioned: "Reach out to. . ." I feel this is an HR overused phrase and it intensely annoys.
Thankfully, I no longer have young adults in the house, but that lingo also made me --great examples above and don't even get me started on the use of the word "like" to begin a sentence.
"I want to follow up with..." I use this at my office all time (when I'm emailing outside agencies when the agencies don't give me what I want) and I hate it.
Also, "jawn". It's a Philly term for "thing". It drives me INSANE. Another reasons I don't go to Philly at all because everyone says "jawn". Ugh.
There is a ambulance chaser commercial here that says, "Whenever I was pulling out of my hotel parking lot, I was hit by a speeding semi." When you were pulling out. Not whenever!
