What does Hila mean?

"That video from yesterday was so hila," she said, laughing out loud.

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 see it in texts and stories about situations that are just too absurd to keep a straight face. Same meaning as in English, half the letters. Also read about sensa, LMAO and gezel.
