Fidget spinner
From Tardis Wiki, the free Doctor Who reference
The fidget spinner was a product popular on Earth in the 2010s. According to Lady Christina de Souza, the fidget spinner came about when she tried selling alien technology to a big tech company on Earth. They reverse-engineered the alien device, caught Christina up in long, drawn-out legal matters, and released various "knock-offs" of the original spinner under different names.
The result was a craze which, in the 2010s, Janice Matheson expressed she had been trying to forget. (AUDIO: Death on the Mile)
