What does HHR stand for on the new Chevy HHR?

I know that the Chevy SSR is Super Sport Roadster. My aunt has an HHR so we are trying to figure out what it stands for.

Its Chevy's new line of crossover cars. I don't think it really stands for anything just like the SRT 10 Dodge Viper Truck, its just a model.
