Pantsdrunk

Pantsdrunk (stylized as Päntsdrunk; kalsarikännit, ) is a form of drinking culture, originating in Finland, in which the drinker consumes alcoholic drinks at home dressed in very little clothing, usually underwear, with no intention of going out. To a large extent, it is still considered a way of life in Finland, possibly related to the stereotyped lack of social contacts among Finns. The forced isolation of people in their own homes caused by the COVID-19 pandemic created a global trend for this drinking habit.
