Starbucks baristas beg you not to order the Unicorn Frappuccino

If you were procrastinating on trying Starbucks' Unicorn Frappuccino, you might be out of luck.

The limited edition drink hit stores earlier this week, and customers seem to be asking for it in waves.

Starbucks baristas have taken to social media to complain about the coffee chain's entry into the latest food craze: Unicorn Frappucino.

Though derided by critics as "magical diabetes juice", the popular and brightly multicolored frappuccino ran out in Northwest Indiana nearly as soon as it was introduced on Wednesday; for instance, it was gone from the Hammond Starbucks on Indianapolis Boulevard by Wednesday night. The video has since been deleted off Twitter, but is still gaining plenty of views on YouTube.

"That's the color I can only describe as tumor", he said as he held one of the drinks for the audience.

In a video - available above - the barista says: "Today I need to rant just a little".

The Starbucks drink is a trendy concoction of sweet pink and sour blue ingredients, topped with whipped cream and sprinkled with "fairy powder" - whatever that is.

"My hands are sticky. I have never been so stressed out in my entire life". I have Unicorn crap all in my hair and on my nose.

In a statement, Starbucks said the company will be reaching out to Burson "to talk about his experience and how to make it better".

The Unicorn Frappuccino is taking newsfeeds by storm, presumably because it was invented for the sheer goal of filling Instagram with cups of multi-colored froth that make Tumblr-enthusiasts squeal and cynical 20-somethings roll their eyes so far into the backs of the head, they go blind.
