Another name for a smoothie. Since smoothies can not always be completely smooth, it calls to question the level of smoothness the said beverage in question has. Therefore, it can also be called a blendie, as one cannot question that it has been blended, but one can question whether or not its texture has been adequately smoothed to earn the title "smoothie".
Dave: Hey man, want to try some of my smoothie?
Matthew: Nah man, you still have ice chunks in it - that's a blendie.
