What does Datediner mean?

For the datediner her dispuut had matched her with a fun date.

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

Students often organise a datediner with their jaarclub, student house or association. Don't know anyone to bring? Then they sometimes set you up with someone. Half blind date, half dinner party. Also read what talking stage means.
