In Finland, what does “kalsarikännit” entail?
The complexities and highly-different structure of the Finnish language mean that there are several words that do not translate directly into English, or, once translated, sound truly odd.
To help clear some of the confusion, the Finnish Tourism Board put together a dictionary (complete with accompanying emojis) of "hard-to-describe Finnish emotions, words, and customs”. Included in that list of words and phrases is “kalsarikännit”.
According to the Tourism Board website, “kalsarikännit” is defined as, "the feeling when you are going to get drunk at home alone, in your underwear, with no intention of going out." (Apparently, partners and close friends can sometimes take part, but the atmosphere should always be relaxed and unpretentious.)
Finland may be the first country to come up with an actual word describing the activity, but it is highly doubtful that they are the only nation practicing it.
There’s even a word for those who are reluctant to participate: “jänishousu”. It means “rabbit pants”, which is essentially the Finnish equivalent of “chicken”.
