It's a brown sugar shaken espresso. The shortened words aren't hard to figure out. Espresso shots can be made regardless of the roast, which is in this case a light roast (blonde espresso). Sure, less traditional, but you can pull shots with any coffee you desire. In this drink, there are several shots shaken with a bit of brown sugar, cinnamon, and ice, served topped with a splash of oatmilk. (It looks like the milk has mixed in over time of being carried.)

A shakerato (shaken espresso) is a real type of coffee drink. Lmao.

Also, if this looks like a 32oz cup to you, you need to open your eyes. 32oz does not fit in the palm of one's hand unless they have much larger than average hands.

Edit: the Gr apparently stands for grande. In Starbucks language: 16oz. Lmao.
