There she sits and her skirt dangles....
dangles hanging off a bridge, dangling 20 feet in the air, tied to a chair, in my boxers!
natty trilby hat, worn at a rakish angle and a cigarette dangles from the corner of his mouth.
There is even a mouse that dangles to encourage your cat to interact and exercise.
Kittens like to play and will bite and swat at anything that dangles.
