Fidget Spinners
How triggering is this picture? Fidget spinners were an insane fad that lasted a little bit too long. They wealsed their way into tons of comedy sketches and editorials on how dumb kids are these days, but at least they pushed a bunch of money into the economy. Fidget spinners can still be found in stores, but it's way less likely to see a mob of kids whipping these things around on the street nowadays.
