I think that could classify as a sundae, as is...
Like, you could drink that, or you could have any 2 meals from McDamnit, in one sitting, and it would possibly work out to the same caloric content.
I'd hate to see the price tag on such a monstrosity, as well... for what it is (vile) Starbucks is like the most overpriced, nasty swill you can name (just, barely, leading anything from McDamnit). When I think coffee, Starschmucks isn't even close to what I am wanting.
