"You're a May bug"

This is an allusion to a German children's song about the cockchafer beetle:


Maikäfer flieg...

Dein Vater ist im Krieg

Deine Mutter ist in Pommerland

Pommerland ist abgebrannt

Maikäfer flieg!


Cockchafer fly...

Your father is at war

Your mother is in Pomerania

Pomerania is burned to the ground

Cockchafer fly!


This song dates back to the early-17th century, when the region of Pomerania was pillaged in the Thirty Years' War. It was commonly sung by children in Germany during the Second World War as the Russian army invaded Germany.
