All that jazz

The previous person who wrote that it came from the musical "All That Jazz" is very wrong. The expression has been used for a LONG, LONG time before that show ever came out. I mean, people I know have been using the expression for as long as I can remember, LONG before anyone ever CONCEIVED of the show named "All That Jazz". It's probably been used since at LEAST the beginning of the 20th Century and probably longer than that. It's another way of saying "and all that stuff". It's a slang way of saying something without telling the whole thing, because telling the whole thing would be boring and monotonous.

From the origin of the hit theatre and film "Chicago" and the song "All that Jazz" is the origin of the saying. It is used on the end of a sentence or list instead of the word "Etc."

A movie quote from 'Chicago', but usually used in slang to mean 'and all that stuff'

all that bullshit, all that stuff, talk, etc.

A term that came to prominence during the coronavirus pandemic of 2020. During this time, disco and funk music was making its comeback (popular new-Disco artists being Dua Lipa, The Weeknd, and Doja Cat) as a result of its feel-good and escapist qualities— leading to minor resurrections of sayings such as “groovy” and “ya dig?” among others.

This also led to a more relaxed and feel-good vocabulary amongst American youth, especially ones in urban areas hit hardest by the pandemic. The term “all the jazz” is not to be mistaken with “all that jazz.” All the jazz is more or less a synonymous mirroring of the term “all the rage,” but with a more relaxed connotation.
