How it's used
Slang terms for money often use water imagery, and this is a classic example of how Hong Kongers refer to currency denominations. It is exclusively used for multiples of one hundred, so you would never use it to describe a single dollar or a thousand dollars. It carries a casual, streetwise tone that is perfect for markets or talking with friends but should be avoided in formal business settings.
Examples
This shirt costs two hundred dollars, it's so expensive.

Common mistake
Learners often mistakenly try to use this for other amounts, but it only functions as a unit for hundreds. You cannot say 一舊水 for one dollar or 五舊水 for five dollars to mean anything other than one hundred or five hundred.
