What it means
Derp functions primarily as an interjection that draws attention to an act of foolishness or stupidity, often uttered after a bone-headed mistake, as illustrated by the Wiktionary example "I put chips in my soup instead of crackers. Derp."
Beyond the interjection, derp can serve as a placeholder for unimportant details ("blah blah blah"), as a verb meaning "to act stupidly or foolishly" or "to make a stupid mistake", and even as a verb describing eyes that point in different directions (strabismus).
As a noun, derp denotes either a person who acts stupidly or foolishly ("a derp"), a stupid mistake or general stupidity, or the rhetorical tactic of constantly repeating an opinion after facts have proved it incorrect, a sense highlighted by economist Noah Smith’s description of "the constant, repetitive reiteration of strong priors" in punditry.
In political commentary the term is used to mock repetitive, debunked arguments, as seen when Josh Barro labeled Erick Erickson "derpy" and Paul Krugman coined "Moral Derpitude" to criticize ideological intransigence.
Affectionately, internet users apply derp to pets exhibiting goofy "derp faces", such as a cat’s cross-eyed stare or a dog’s tongue-out grin, turning the insult into a term of endearment for lovable clumsiness. [1][2][3][4][5][6]

Why it's everywhere
Nostalgia for early-2010s meme culture keeps derp alive in retro posts, where users treat it as an ironic throw-back that signals shared awareness of how quickly internet slang ages.
Meme-history discussions, quiz content and "throwback Thursday" posts frequently cite derp as a case study, reinforcing its status as a cultural artifact of the rage-comic era.
The term resurfaces in political commentary when commentators label repetitive, debunked arguments as "derpy" or invoke "Moral Derpitude," showing that the word’s rhetorical sense remains relevant in online debate.
Pet-centric social media posts, showing cats, dogs or other animals with goofy "derp faces", have created a affectionate sub-usage that appears regularly in platforms such as Reddit, X and YouTube, as evidenced by recent posts like "princess donut’s derp face is too good to be true" and "Daily dose of cats being derps."
The 2013 Oxford Dictionaries Online entry and the 2014 Gawker editor’s memo banning derp (along with lulz, amazeballs and ftw) sparked renewed discussion about the word’s legitimacy, giving it a meta-trend as linguists and media critics debate whether internet slang belongs in respectable publications.
Search-interest data shows a spike in July 2012, coinciding with the U.S. presidential campaign, indicating that derp was repeatedly invoked in political memes and commentary during that election cycle.
How to use it
Mostly nostalgic or ironic; using it to call someone stupid feels dated, while referencing it in meme-history contexts is understood as a throw-back.
