How much time do you have?? LOL -- I could go on and on.
I agree, "reach out" is overused so it's annoying.
I agree with A.L. about "like" - I used to emphasize that when I was teaching Spanish, putting the word for "like" in every sentence about 20 times and then asking the kids to translate it. They got confused, of course, at which point I suggested that it might be hard for people to follow their nonsensical use of "like" all the time.
I love B's answer about what the company says before they eliminate your department!
My personal nails-on-the-blackboard phrase: "I could care less." People just don't know that it means "I care, at least a little."
I also had the Double Is: "The problem is is that the project is too expensive." "The thing of it is, is that I hate that guy." There are very few instances where there are 2 "is" words correctly used, such as "The question is, Is he going to agree to it?" But people do it all the time.
Both "like" and the extra "is", along with some of the phrases listed by other posters (like "and such") are FILLERS that people put it to fill the silence. If they would slow down and create a real sentence, they'd be clearer.
Commercials with errors bother me because, presumably, they hired a professional writer to come up with the words. Mispronunciations bug me, like "real-a-tor" instead of realtor, "jule-ery" instead of jewelry, and the ridiculous "nuke-u-lar" instead of nuclear. There's a commercial now with a voice over saying "As a stay at home mom, this is really important." No, the thing is not the SAHM. I am the SAHM so the wording should be "As a SAHM, I know that safety is important."
I have a friend who ends every sentence with "blah blah BLAH" - it's an effective way to not finish the thought but still keep the "floor" so no one else can respond, without really explaining the rest of what she's thinking. But it's not effective in communicating anything.
"But" pretty much wipes out what you just said in the first part of the sentence: "I know you work hard for our family and you mean well, BUT…."
And the word "just" is almost always used to belittle someone else's position or feelings: "It was JUST a joke" or "I was JUST kidding." ("So get over it, you overly sensitive marshmallow" is what that says to me.)
And I agree with the post below about "my bad" - it's not nearly as powerful as "I'm sorry" but people use it to halfway admit a mistake without actually apologizing.
