[Ads-l] Lewis Porter on the origins of "jazz"

[Z Rice]

Porter states in his writeup on "jazz":

"Although a similar evolution happened to the word “jazz,” which became
slang for the act of sex, that did not happen until 1918 at the earliest."

However, Porter doesn't mention what exactly the 1918 citation is or where
it comes from. Does anyone have that information?
