The term derpy is synonymous to the words random, silly, idiotic and stupid, being an adjective version of the word derp.
Derp was created by the masterminds behind the Tv series South Park, Trey Parker and Matt Stone.
It is first heard in their film, titled Basketball, where they are caught sniffing women’s underwear and Matt leaves the room, running, dropping the beautiful expression that is derp.
It didn’t just stop there, with the appearance of Mr. Derp in South Park, and the term reappearing several times during the lifetime of the show, with moments like the parody of Rob Schneider’s film trailer in the episode “The Biggest Douche of the Universe”.
The first Urban Dictionary entry was added on derp in 2003. Since then, it has been featured in 4chan’s image macros, as well as the well-known rage comics, with characters called Derp and Derpina.
Characters seen with the text derp around them are usually portrayed with eyes looking into two separate directions.
The term derpy has derived from the base word during the last 20 years and its use in mainstream English is growing slowly but steadily.
