The term fidget spinner is a generic name to describe the toys, which are usually made of plastic and contain one or more metal bushings on which the outer piece spins; some also contain lights and other battery - operated features.
I worried that one slip - up on my part — one uncool multisyllabic science term, one admission that I don't know what a fidgetspinner is — would permanently label me in their eyes as one more boring and out - of - touch adult.
