How it's used

This term is the standard colloquial way to refer to a mouth ulcer in Hong Kong. It is often associated with the concept of heatiness in traditional Chinese medicine, where people believe consuming too much fried or spicy food triggers these sores. You will frequently hear people complain about it after a period of poor sleep or stress.

Common mistake

Do not confuse this with the literal insect, as the term uses the word for a type of flea or louse metaphorically to describe the stinging, itchy sensation of the ulcer. It is strictly a noun phrase and cannot be used as a verb to describe the act of causing an ulcer.
