Beating A Dead Horse
Published September 24, 2026
"Beating a Dead Horse" is an English idiom used online to call out a joke, argument, or discussion topic that has been repeated well past the point of being useful. The phrase traces back to a British parliamentary speech from 1867 but found new life on forums, webcomics, and image macro sites starting in the early 2000s.
Overview
"Beating a Dead Horse," also written as "flogging a dead horse," is an English idiom used online to signal that a joke, argument, or discussion topic has been beaten to exhaustion1. Forum posters and Redditors drop the phrase into replies when a running gag has stopped being funny, or when a debate keeps circling back to the same points4.
The idea shows up as plain text in comment threads and as reaction comics of a literal figure whacking a horse carcass with a stick. Webcomics such as Penny Arcade have run the gag as a straight visual punchline aimed at industry habits like endless game rereleases2.
