当海绵宝宝遇上灰太狼
[dāng hăi mián băo băo yù shàng huī tài láng]
This translates to 'When SpongeBob Meets Big Bad Wolf (Grey Wolf)', where SpongeBob is a naive and cheerful character while the wolf represents cunning and mischief. The nickname may imply unexpected encounters between two different people or an amusing situation where opposites meet.
