Goof

Generically, the word goof is another term for a mistake. However, the term is also used in a number of specific senses. The actual origin of the word is unknown, but several origins have been conjectured. According to Merriam-Webster, "goof" is likely a variation of "goff" in an English dialect, meaning simpleton. Some say the word may come from an identically pronounced Hebrew word meaning "body". Others believe that it was inspired by the Disney character, Goofy (though it is more likely that the character got his name from the word, not the word from the character).

There is a Spanish word, "gofio," which refers to the balls of toasted flour and salt eaten by the original inhabitants of the Canary Islands. In Latin America (esp. Cuba) the word "comegofio" (lit. "gofio-eater") came to refer to anyone from the Canaries, stereotyped as primitive or stupid.

Cinema

In filmmaking, a goof is a mistake made during film production that finds its way into the final released picture. Depending upon the film and the actual scene, the goof may have different effects: a loss in realism, an annoyance, or it could just be funny. It is often a type of continuity error. Goofs are also known as "bloopers" or "mistakes".
