A partially frozen desert item experiencing the transition from a solid to a liquid. Solid + liquid = saquid. The concept was pioneered in a Wendy's add campaing for their frosty dairy desert. The term is ofen paired with the word fpoon, which is a derivation of "frozen spoon."
My girlfriend was on her way over so I asked her to stop by Wendy's and bring me a saquid and not forget the fpoon, but they only had chocolate flavor and it wasnt as good as it looked on T.V.
