*Flogging a dead horse* (alternatively *beating a dead horse*, or 
*beating a dead dog* in some parts of the Anglophone 
<https://en.wikipedia.org/wiki/English-speaking_world> world) is an 
idiom <https://en.wikipedia.org/wiki/Idiom> that means a particular 
request or line of conversation is already foreclosed or otherwise 
resolved, and any attempt to continue it is futile; or that to continue 
in any endeavour (physical, mental, etc.) is a waste of time as the 
outcome is already decided.
