Where did the term "spaghetti western" come from?

The term originated in the 1960s, when it was cheaper to make movies in Italy than the United States. Moviemakers made their westerns there and had English dubbed in for the Italian actors. That’s how Clint Eastwood’s early movies were made. One definition we found for spaghetti western is “a European western, usually filmed in Spain or Italy, and popularized in the 1960s by the films of Sergio Leone.” Leone’s films, in case you’re interested, included The Good, the Bad, and the Ugly (1966), starring Eastwood. His last film was a mob movie called Once Upon a Time in America (1984).
