Don’t do it!

A meteorologist in Iowa has gone viral after urging the young (and the young at heart) not to eat icicles this winter, for a few nauseating reasons.

Katie Nickolaou is a meteorologist KMEG in Sioux City and recently released a practical PSA on TikTok explaining why it’s a bad idea to eat ice spikes hanging off houses or gutters, no matter how much they look a Popsicle from a winter wonderland.

Don’t eat icicles! Please respect the fact that I edited out the original woman in the video (I have her permission) #IciclePoop

COOLER TEMPERATURES IN THE SOUTHEAST AND FLORIDA, ACTIVE WEATHER IN THE WEST  

The quick clip began with a shot of a woman pulling an icicle off a roof and eating it like a carrot, as Nickolaou exclaimed, "Please don’t do that! I’m a meteorologist — I should know."

"When icicles form, it’s from water that melts off of your roof and runs down the side of a building. Well, here’s the thing – you know what else is on your roof? Bird poop. A lot of it," she said.

"And that water picks it up and freezes it in the ice," Nickolaou continued, brandishing an icicle. "You’re eating poop!"

The winter warning has since been viewed 12 million times on TikTok, but the meteorologist told Fox News that she’s shocked the video has gone so far and wide.

"I've seen videos circulating on social media of people eating icicles for a few weeks now. I always love telling people weather facts, so this seemed like the perfect opportunity to spread some funny, geeky knowledge," Nickolaou said on Monday. "I never thought it would go viral!"

Joking that it was "very strange" for the quick clip to receive such overnight hype, the storm chaser said that fans should stay tuned on her social media pages for more wild weather updates in the months ahead.

"I’m just glad that so many people are interested in learning more wild weather facts!" Nickolaou added.

However, some seasonal skeptics claim they won’t be taking the advice.

"Gotta keep the immune system strong," one joked.  

"Interesting (crunch crunch)" quipped another, who apparently enjoyed eating the icy treats.
