The expression to nail something usually means to "to achieve something or do something right". (informal)
The expression "the sh*t out of" is used to "emphasize the degree of force of an action that you are describing" (Cambridge)
I was wondering if it sounded natural to native speakers to say, "nail the sh*t out of something", essentially mixing the two expressions to sound more emphatic, as in:
She nailed the shit out of the chorus
he nailed the shit out of writing that piece of code.
