The Krampus tradition, whilst once done with a modicum of sobriety is now used as an enormously great excuse to get completely inebriated. Think of it as an old Europe version of Spring Break but, alcohol aside, with slightly different preoccupations and - of course - at a different time of year. Very well, just think of it as an excuse for young people to behave badly.
