The word "heiney" is a slang term used to refer to the buttocks or the rear end. It is considered an American English colloquialism. While the precise etymology of the word "heiney" is uncertain, it seems to have originated and gained popularity in the early to mid-20th century.
One theory suggests that "heiney" might have derived from "Hiney" or "Hynie", a variant of the word "hinder", meaning the rear part. Another possibility is that it originated from Yiddish, where the word "heinie" (העייני) is used to indicate the buttocks. This is supported by the fact that Yiddish terms often found their way into American English discourse. However, concrete evidence for this theory is lacking.
