[Idiom] fan your ears

[wildcat56]

hello, I would like to know what exactly means "fan your ears" thank yoiu

Where did you hear/see this? Could you give us some more context?

The only thing that spring to mind is the mechanism used by elephants to cool down. They fan their ears to get rid of heat. Does the context involve someone getting annoyed?
