the beating refers to the overusing of the "dead horse". Said horse is a metaphor for a joke, and the fact that it's no longer living implies that it's no longer funny
person1:hey...is that a dead horse
person2:uhhh.....yyy..yes i believe it is...why do you ask?
person1:oh no reason...say...you wouldn't wanna beat that dead horse would you?
person2:i thought you'd never ask
persons1+2 proceed in beating the dead horse
five minutes later, cop enters
cop:hey are you beating that dead horse?
persons1+2:yes...
cop:...well...care if i join you?

cop starts shooting horse whilst the tho persons continue to beat it with sticks, fade to black, THE MORE YOU KNOW enters along with someone from Friends talkin' about some stupid crap.THE END...But is that really the end?...Yes, yes it is...Or is it?

Henry: "Yeah bro me and my friends were all sitting around a fire, just beating the dead horse!"
Joe: "Be careful man! If you beat the dead horse too much you could get a 90 degree angle cock from that!"
Henry: "You only get one life joe, live it up."

Beating a dead horse is alot loke selling out- you just go a bit overboard with it. If people say you're beating a dead horse, you need to stop what you're doing ad re-evaluate your decisions.

To continue trying to beat off a horse when it clearly isn't going to work anymore due to lack of blood flow.
Dude: I was out beating off a dead horse last night, but may hand started to cramp up, so i just went home instead.
