To be astonishingly scared. Being millered is the highest amount of being afraid one can be. Should only be used to describe unprecedented terrifying circumstances.
Can be used as a describing word for anything that is completely fucked, whether it be a paroletic person, broken fence or written off car, anything that falls disgustingly short of satisfactory is millered.
