Go down like a lead balloon
English Idiom
Meaning: When something fails completely or is not well-received, often unexpectedly. It's akin to an idea or action that sinks rapidly and disappoints the expectations of those involved.
Origin: The idiom 'Go down like a lead balloon' originated in the mid-20th century and is likely a play on the fact that lead, being very dense, would not float but rather sink rapidly if it were a balloon. This imagery was used to convey the idea of something that fails spectacularly. The phrase gained popularity in English-speaking countries and has since become a common way to describe unsuccessful endeavors.
