Definitions

Etymology: "Durr" is a spelling variant of "duh", and its history lies in the sound it imitates rather than in any older word. The interjection is used to mock a statement that is obvious, or to call someone dim for saying it. It works by pretending to be the speech of someone who is slow to understand, so the joke depends on the listener recognising the caricature. The sound is intended to represent the speech of an intellectually disabled person, and the mockery is aimed at stupidity by way of that imitation. Because the word is built on a caricature instead of a root, there is no earlier English form or foreign source to trace, and the meaning comes entirely from the way the sound is performed.
