What does Maat mean?

"Thanks maat, that really helped," he said to his housemate, relieved.

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

Students use it in almost every casual situation to talk to a friend. It works just like "mate" in British English. Close relatives: kompaan and gozer. Also read what mattie means.
