Of yumminess

I say that the qualifier "yummy" refers solely to quality of taste and cannot be perceived while the substance in question is actually in one's tummy, as tummies are not equipped with taste buds. Jason contends that both satiety and texture should also be taken into account when measuring yumminess levels, and said yumminess can thus to some extent exist within the tummy. What is your educated and informed opinion on the matter?
