Claptrap
Etymology
A vividly literal theatrical coinage of the 1700s: a "clap trap" was a device or showy line in a play designed to "trap" applause — a clap — from the audience. It named a cheap trick for winning approval, then broadened to any high-sounding but hollow speech. The mechanism is right there in the word: language built to catch applause, not to say anything.
noun · /KLAP-trap/
Showy, pretentious language that is essentially meaningless.
What it names
Talk engineered to impress rather than inform — the empty flourish that exists only to win a reaction.
Example
Strip away the visionary claptrap and the strategy was just "spend more on ads."
