The sneak in like a mosquito in the night through a hole in the screen. It starts with a little word or phrase in the news that sounds a little strange, or focus group-y. My ears prickle slightly, and almost subconsciously I think, "stand by for a barrage of naked propaganda".
Within an hour every news outlet in the country is saying the new word or phrase. Funny how that works. By breakfast, I'll hear the words falling from the lips of ordinary people.
A couple of recent examples:
"job creators" (Ex. "don't tax the job creators")
"blank check" (Ex. "that would be like giving the President a blank check")
Yep, they're focus group words, gotta be. They are first tested on groups of people just like a company would test names for a new product, then they are released!
They are laughably bad propaganda words, but they fly like the wind.
