Idiom: “Beating a
dead horse”

Example:
Minami:  Hey there
Mariela.  I heard you were talking to
Joyce about politics yesterday, and you told her to “stop beating a dead horse”.  I
mean I don’t know much about politics, but I can’t imagine anyone wanting to do
something as cruel as that!  Why would
she beat a dead horse?  That’s horrible!
Mariela:  Minami, you
silly goose!  “Beating a dead horse” is an English idiom.
Minami:  Really?  That’s pretty strange.  What the heck does it mean?
Mariela:  It means
repeating something over and over again, trying to make your point in so many different
ways that it becomes totally obvious.
Minami:  Oh, I think I
get it.  I just don’t understand why
English idioms use so many references to animals.  They are very confusing to me! 

Meaning: “Beating a dead horse” is a common idiom has nothing to do with cruelty to animals, dead or alive, but simply means to make your point over and over again ad nauseam!  (Basically, this means to keep explaining and giving examples about something to the point of making your audience sick to their stomachs!).
