How it's used
Refers specifically to nasal discharge in a very informal, often slightly crude or childish way. It is rarely used in polite or professional settings where the more neutral term 鼻涕 is preferred. Expect to hear it mostly among friends or when talking about children.

Common mistake
Do not confuse this with 鼻涕, which is the standard term for snot. Using 泗 in a formal context can sound overly blunt or unrefined.
