In commercials:
[ul]“clinically proven” - puh-leese
[/ul]
[ul]
[li]“clinically tested” - likewise[/li][/ul]
In general conversation: [ul]
[li]“awesome” - The usage quota on that word is off the chart. It’s worn out and used up. It’s an empty, dried-out husk of a word. It should be allowed to retire to a chair in the sun on an island far, far from people who speak. [/li][/ul]
[ul]
[li]“iconic” - enough already [/li][/ul]
“100% natural!” Yeah, so is arsenic and dog shit. What else you got?
“Utilize” – just say “use”, you pompous twit!
“Educator” - Teacher is a fine and noble title/profession; educator is pretentious.
Nose to tail.
Add to that: “significant” or “significantly” , most often heard in TV commercials, as in: Brand-AAA Aspirin significantly [blah, blah…]
That is, using these words in their statistical meaning, which may be technically correct but doesn’t mean the same thing as the “common everyday” meaning, and is really used for the purpose of “significantly” bamboozling viewers.
ETA: None of these usages are going to go away, of course. They use words like those on purpose! Significantly more people get bamboozled that way.
ETA some more: And I wish news writers would learn the difference between “stanch” and “staunch” and use them correctly.
WAKE UP!! Always in caps, always with the exclamation points, always screamed in-your-face by right-wing religious nutters. As in WAKE UP AMERICA!!..WAKE UP SHEEPLE!! Jeebus is coming!! The ship of state is going under!! It’s everywhere…on amateur illiterate blogs, in the comment sections of news sources, hell, there are whole websites devoted to telling me to WAKE UP!!. This isn’t just a dog whistle for the wingnuts it’s a gawdam cattle call.
If one more nitwit screams WAKE UP!! at me I’m going to…I’m gonna…
I dunno…
Go back to sleep?

24/7 - especially when followed by “all the time” or some variant.
Fanbois.
State of the Art = totally gibberish.
How about any modifier applied to “unique” or “ubiquitous”?
That’s above my pay-grade.
OK, if you are in the military, I understand. I still don’t like it, but in the military they actually have pay-grades.
In business, you don’t. And, that’s not what they mean anyway. What they mean is “That’s for people above my place in the hierarchy”. While sometimes (OK, usually) this means folks getting paid more than you, it isn’t the money, it is where you are on the ladder. It would probably me more accurate to say “that’s for people who are smarter than I”.
Grrrr.
excavating (for a mind)
Typing “LOL” is the internet version of chewing gum: it instantly lowers your IQ by 50 points and makes you someone whose opinion is not worth reading.
In my company, a very well known global giant, there are paygrades. And, while true, that the term is used to refer to people higher in the hierarchy, I have seen painfully few times when it meant ‘smarter’.
I would like to ban the word “conversate” (although if I stopped watching The People’s Court, I would probably never hear it again).
So damn baby, you’re already down 100 points! Way to go on your spelling!! You did a super job! 
Since it seems we’re banning “non-words” now; I want to ban supposably and his inbred brother supposively.
And esculator and perculator (for escalator and percolator).
“face time”
“real time”
“tweet”
“Network” as a verb.
I am L’ing out L.
How about “imput” instead of “input.” If people knew what the word meant, they might figure out that it has to do with what goes IN, and that “IM” makes no sense. Or not.
And, as long as we’re on the subject, it’s BUCK-naked, not BUTT-naked.
