BOSTON (CBS/AP) – The internet has lost its mind over the limited-edition Unicorn Frappuccino – and apparently so have Starbucks baristas.

The sugary frozen drink that changes flavor and color with a stir of the straw debuted on Wednesday and is only available until Sunday.

A 19-year-old Starbucks barista in Colorado described the “insane” scene at his location.

“I have never been so stressed out in my entire life,” Braden Burson said in a video that went viral. “My hands are completely sticky.”

He says people were coming in left and right on Wednesday.

“If you love us as baristas, don’t order it,” he said. “For the love of God and everything that is good, don’t get the Unicorn Frappuccino!”

Burson tells The Associated Press that he didn’t think he would get this much publicity and he didn’t intend to “downgrade” the drink.

“It’s a great drink. But it is difficult to make when there are like 20 fraps all at once both front and drive thru,” he wrote in a Facebook message.

Starbucks says in a statement it’s reaching out to Burson “to talk about his experience and how to make it better.”

But his rant is clearly resonating with some fellow baristas.
