It is a famous saying of a Mathematics teacher in La Salle College, Hong Kong. He used it to express his dissatisfaction on students who packed their school bags before the bell even rings. In normal conditions, it can be used to question someone who is going away to obviously nowhere for the purpose of avoiding something deliberately.
