A day when military personnel do not have to punish the bad guys from their whirling beast of death. Nor do they have to brush their teeth or put on their combat boots. They can lounge around all day doing nothing at all.
One military member, we'll call him OAF for Ops Air Force, once slept 18 hours on sloth day and was only nourished by 5 meat rolls, 2 chicken wings, a light chef salad, and 3 Ripits.
