So I was drinking a milkshake as part of my new diet this weekend, and started mouthing the words to Kelis' Milkshake to Alric, a la one of the Olsen twins and Avril Lavigne at the end of New York Minute, but Alric had never heard of any of that! This ignorance of course is to be contrasted with the whimsical conversations we have at school about the exact figurative status of "milkshake" in said song. It could be metonymic euphemism, though parsed (not parched).
