"To flog a dead horse" is the English equivalent to "to beat a dead horse", which means to do something over and over again when it is not necessary, whether it be saying something or doing something.
Though considered abusive, in the past people beat a horse to make it move and do heavy work. Obviously, this measure only worked on living animals; because it hurt, the horse moved. So "don't beat a dead horse" or "you're flogging a dead horse" means you keep trying to force something that just won't happen. Another expression, "The horse is dead--go back to bed!" means you might as well give up because what you want to make happen won't happen.
This is a horse term. Flogging is beating with a whip. It does no good to beat a horse that is dead, because it will never get back up and work for you.
Don't flog a dead horse.
- My efforts are futile - Pissing in the wind (Australian slang) etc. bark at the moon catch at shadows bite a file beat the air in vain plough the air etc.
That is to flog.
Not to be crude but I think flog your log is a euphemism for masturbation....like spank the monkey or choke the chicken.
"When the horse is dead, get off" means you should not waste time on things that are not worth it. If the horse is dead, you can't ride it any more.
Did you mean frog? If you did, no, it's an amphibian.
The actual quote is "stop beating a dead horse" stop wasteing time on a pointless activity.
It's a way to say "to masturbate".
