What does Batsen mean?

After the party she hinted that she had been batsen that night.

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

You mostly hear it in stories about a night out where things went further than just kissing. It is casual and a bit cheeky. Not a word for the family dinner table. Also read about berig and hookup.
