A coma week is a week in which the participant will spend the entire time
drunk - going out every
night of the week, getting
drunk, returning home, sleeping and then eating a fry up and starting drinking again in preparation for the next night of drunkenness.
It is so named because after 7 days of near-constant drinking, the participant will be in a state that resembles a coma - unconscious and unresponsive to stimuli
