“I think the craze disappeared in a year because it gave people headaches.”

(I recently found my hair feather collection; what a time.)

Here are some of the short-lived trends they mentioned.

“Remember in the early 2010s when there was a frozen yogurt place on every block?

Two or three years later, they all seemed to vanish, and nobody wanted froyo.”

“Cup stacking was big for a minute.

Three people wearing Google Glass smile while looking at something off-camera

The middle school even had cup-stacking competitions after school.”

“The fidget spinner craze was wild!

It’s like they went from ‘Look at me, I’m stress-relieving!’

Nine colorful rubber bands shaped like Hello Kitty faces, a bow, an apple, "HK", and other playful designs, arranged on a wooden surface

to ‘Why do I have 12 of these?’

faster than you’re able to say, ‘What was I thinking?'”

“The whole 3D craze back in like 2010.

Everybody thought it was the future afterAvatarcame out in theaters.

EVERY movie tried to be 3D.

Blue and black dress hanging in a store, famously known from the internet debate over whether the dress is perceived as black and blue or white and gold

After that, there were 3D TVs, 3D phones, and the Nintendo 3DS.

I think the craze disappeared in a year because it gave people headaches.”

“Guys wearing two polo shirts and popping up both collars.”

I worked at a PacSun at the time, and we sold SO MANY of those.”
