What does Miemelen mean?

"Stop miemelen and grab another beer," she said, laughing.

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 use it when someone is complaining about something small that doesn't need to be taken too seriously. Every student house has someone who loves to miemelen about the dishes. Also read about salty, yap and bits.
