Bite the dust
Meaning:
Fall to the ground, wounded or dead.
Origin
Given the many B-feature cowboy movies in which the bad guys, or occasionally the pesky redskins, would 'bite the dust', we might expect this to be of American origin. It isn't though. The same notion is expressed in the earlier phrase 'lick the dust', from the Bible, where there are several uses of it, including Psalms 72 (King James Version):
se uno intende il matrimonio come una caduta/decesso allora credo che sipossa estendere il significato a
sposarsi
