Noun. A surly, pretentious, unattractive barista employed at a corporate coffee house who displays heaping amounts of hubris, judgment and attitude when it comes to your lack of knowledge about their sizes and specialty drinks.
"That Ratchanista Barista got all huffy when I didn't know what a Grande Caramel Machiatto was and she gave me an attitude."
