1998's "BASEketball" may not have been a cinematic masterpiece, but it did contribute one word to the English lexicon: "derp."
"Derp" is defined by Oxford — yes, "derp" is in the dictionary — as "a substitute for speech regarded as meaningless or stupid" that can be used "to comment on a foolish or stupid action."
The film, starring "South Park" creators Trey Parker and Matt Stone, features the first known instance of "derp" in this somewhat raunchy scene.
In the years that followed, Parker and Stone wove "derp" into several episodes of "South Park," but the word lay mostly dormant until around 2007, when it began popping up in online memes and internet comments, according to Know Your Meme.
"Peak derp," as New York Magazine put it, seems to have been reached around 2013, when journalists from Business Insider's Josh Barro to CNN's Jake Tapper and The New York Times' Paul Krugman all used variations of "derp" in columns and tweets.
The word has proved surprisingly versatile, functioning as an interjection, an adjective (derpy), a concrete noun (he's a real derp), an abstract noun (the age of derp), and even a verb (derping it up).
