ditsy
Flighty and unfocused
Ditsy describes someone who seems scatterbrained, flighty, or airheaded—easily distracted and not quite mentally present: She played the ditsy blonde in every sitcom.
The word carries gendered connotations, applied almost exclusively to women and girls, often dismissively.
Also spelled ditzy.
