If one thing makes my skin crawl it is jargon. People jabbering on using lots of words as shorthand irritate me. And they could irritate your audience.  Say no to jargon in your marketing copy (unless you are making fun--that is OK in my book).  Advertising Age has a<a title="Ad Age Jargon" href="https://adage.com/bookoftens2010/article?article_id=147583" target="_blank"> list of ten of the "jargoniest jargon" of 2010</a> although some of these aren't jargon (at the end of the day is more a saying).  My list would also include:
<ul>
	<li>Sweet spot</li>
	<li>"Obamacare"</li>
	<li>"Mama Grizzlies"</li>
	<li>Going viral</li>
	<li>Get your ducks in a row</li>
	<li>Going out of pocket</li>
	<li>Drill down</li>
</ul>
I will admit to having used some jargon at some time.  However, you will never ever hear me use the word "terrific." I know it is not jargon, but I despise it nonetheless.  It sounds so 1970s to me.

What words or phrases get your goat (ha ha, I had to throw something in)? What makes you scratch your chin and say huh? What gets your panties up in a bunch?
