Talkin' 'bout my generation

Today my daughter was dancing to that song that stutters "Chaka Khan, Chaka Chaka, Chaka Khan, Chaka Khan" throughout (called "I Feel for You"), and she was doing a great job (she finally has rhythm, which once worried the spouse and I since my wife couldn't catch a beat if she had the entire Marine Corps. at her disposal, poor dear), so I shouted, "Get down!"

In spectacular duck-and-cover fashion, she hit the deck immediately and looked up at me to see what the hell she was ducking for.

After I was able to stop laughing, I of course explained this was yet another figure of speech and it meant, "Dance!"

English - she is a funny language, no?
