Used to describe a babe with bodacious tatas or a bangin' posterior; particularly a dime so hot that you can barely suppress the thought of using one of her boobs as a bicycle seat. Often abbreviated "HMD."
guy1: "Have you met that new girl in the office? what a babe!"
guy2: "yeah man, old news, she's a total hottie of mass destruction."
guy1: "an HMD, as it were."
guy2: "word."
