Definition & Meaning of "toff"in English

What is the origin of the term "toff" and how is it used?

"Toff" is British slang that appeared in the early 19th century, likely derived from "tuft," referring to the ornamental gold tassels worn by wealthy or aristocratic students at elite schools. The word came to describe a rich or upper-class person, often implying that they are posh, privileged, or out of touch with ordinary people.
