It seems like there are constantly new “trends” that are supposedly happening everywhere . . . and they’re spreading like WILDFIRE thanks to social media.

But some of those trends seem to disappear just as quickly as they arrived, and are less like a wildfire and more like a MATCH when you’re trying to light birthday candles. (???)

Someone recently asked the internet, “What ‘trend’ died so fast, that you can hardly call it a trend?” Here are some of the best responses:

1. Back in the ’90s, when some kids were walking around with pacifiers in their mouths and hanging around their necks.

2. When the poo emoji was on everything . . . clothes, toys, and even treats.

3. (And) when there were mustaches on everything.

4. “Gangnam Style” by Psy. Sure, there will ALWAYS be one-hit wonders . . . but this one seems to have completely disappeared.

5. Flash mobs.

6. Anything from Spencer’s . . . selfie sticks, fidget spinners, and salt lamps.

7. Backwards clothes a-la Kris Kross.

8. Planking. Also, “Tebowing.”

9. Segways. And “hover” boards.

10. The Flappy Bird game.
