"Frappe" is, I think, a term from the effete Easterners. Back when I was growing up in the Midwest, we called 'em milkshakes. To make one, you first fed a cow the flavor you wanted (garlic is good) and the got her really, really cold. Wearing gloves (it's udderly awful to get your fingers frozen to the cow), you milked her into your milkshake glass. Since the stuff was so thick this was difficult, and the difficulty was compounded by the shivering of the cow, the moving "faucets," and often by an irate dairy farmer.

Way into the Effete East, in Massachu...Masa...Far Southern Vermont, my wife says they were called "Awful-Awfuls" at the friendly local Friendly's.
