How it's used
This term is a playful, self-deprecating way to describe sugary beverages that provide little nutritional value. It reflects a common cultural obsession with bubble tea in Hong Kong, where people often jokingly acknowledge that their drink choice is unhealthy while consuming it anyway. The term is almost exclusively used for cold, sweet drinks sold at tea shops rather than packaged sodas or juices.

Common mistake
Do not use this term to refer to actual wastewater or sewage, which is also called 廢水 in formal written Chinese. In a casual conversation, the context of bubble tea shops will make the meaning clear, but avoid using it in professional or environmental discussions.
