rattlebrained
Easily distracted person
Rattlebrained means scatterbrained or flighty—unable to focus or think clearly.
The image is of a head so empty that thoughts rattle around loosely inside: She's too rattlebrained to be trusted with the details.
The word is informal and mildly insulting, suggesting someone frivolous rather than stupid.
