I remember when I first heard that word – I wrote a post about it.  There is a definite Starbuckian language, but have you noticed that there are different dialects of Starbuckian?  You can go to a Starbucks, order a particular drink in the best Starbuckian you know – then go to a different one, order it the same way and maybe get a totally different drink.  Sometimes you can get charged different prices for the same drink at a different locations.  You can be charged for extra milk in some places and other places give it to you for free.  So learn Starbuckian, but also realize that each location has a dialect.
