Who coined the phrase business in front party back?

The origin of the phrase "business in the front, party in the back" is actually unknown. There isn't a single person credited with coining the phrase.

However, the phrase itself likely originated from the popular hairstyle of the 1980s called the mullet. This hairstyle, with its short, business-like front and longer, party-like back, embodies the meaning of the phrase.

While the exact origin remains elusive, the phrase became widely used in the 1980s and 90s as a humorous way to describe the mullet and its contrast in styles.
