Definition of the word hot stuff

The origin of the phrase "hot stuff" can be traced back to the early 1900s, specifically the jazz music scene that emerged during this time. The term was used as a descriptive adjective for highly energetic, thrilling, and electrifying performances by jazz musicians, particularly in regard to their playing style and the intensity of their music. The phrase "hot stuff" likely originated from the use of slang words like "hot" to signify that things were happening quickly, fiercely, or with excitement, and "stuff" as a general term for things, in this case, being used to mean music or entertainment. The expression quickly caught on and became part of the vernacular, eventually finding its way into broader popular culture as a general term for anything that is exciting, appealing, or of high quality.
