What does Krokant mean?

After that comment the atmosphere at the table suddenly got very krokant.

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

The word describes an uncomfortable or tense situation, like a borrel that just isn't working. You can also feel krokant yourself after embarrassing yourself. Close to cringe. Also read what out of pocket means.
