Acronym for 'Fuck It & Sleep In'

You know, the days when you wake up feeling overwhelmed: You have a headache. You've hardly slept because the neighbors were fighting/having sex/getting raided by the cops, you awoke early to the sound of barking dogs and vomiting drunks walking home from the club, You forgot to change your alarm clock for daylight savings and it went off an hour early, at breakfast time there's no toast because the bread is mouldy, no cereal because the milk has turned, no porridge because the rat in the cupboard ate it, and no chance of a McMuffin because you've lost your wallet. You hate your boss, the new departmental manager has been on your back for weeks, the customers are giving you the irrits, you suffer from anxiety from having to deal with the people in Human Resources, and it all just gets a little bit too much....
