What does Cappu mean?

On the terrace she quickly ordered a cappu before the lecture started.

Dutch student slang. This is a Dutch word. You will hear it a lot at Dutch universities, student associations and in student houses.

Next to the classic version with cow's milk there are oat, soy, coconut and almond ones too. Each with their own fans. A cappu before class is a ritual for half the students in the country. Also read about esma and UB.
