Definition of the word doh

The word "doh" is a slang term often associated with the American animated television series "The Simpsons." Its origin can be traced back to the show's creator, Matt Groening, who Inserted the word into the show's script in the early seasons. Groening has explained that the word "doh" was inspired by the sound a cat makes in frustration when it can't paw a pesky toy out of reach. The character who popularized the usage of "doh" on the show is Homer Simpson, who utters the word in a variety of situations, commonly when realizing he's made a mistake or forgotten something important. The casual, somewhat ridiculous delivery of the word has made it a popular mockery of intellectual incompetence in popular culture. Additionally, "doh" has been used outside of "The Simpsons" in popular lexicons, both as a verb and noun. For example, "Yoda created a doh moment for Luke Skywalker in 'The Empire Strikes Back.'" In this context, "doh" is used to describe an embarrassing or significant mistake. In summary, the origin of "doh" can be traced back to Matt Groening's personal experience with cats before he added it to the show's script, which has since become an essential part of American pop culture lexicon.
