falls flat on one's face

Bombs in public

To fall flat on one's face is to fail completely and publicly, often after confident effort.

The image is of someone pitching forward in an undignified sprawl: He predicted victory but fell flat on his face when the results came in.

The phrase emphasizes humiliation—not just failure, but failure that others witness.
