What is the origin of the phrase forget about it?

The phrase "forget about it," often used to express dismissal or to indicate that something is not worth worrying about, has roots in Italian-American slang. It became popular in the mid-20th century, particularly in New York City, where Italian immigrants influenced local dialects. The phrase captures a sense of nonchalance and is frequently associated with the casual, laid-back attitude of urban life. Its widespread use in films and media has solidified its place in American vernacular.
