"Pantsdrunk" (or "Alkoilija" in Finnish) is a Finnish activity that involves drinking at home alone in your underwear, or "pantsdrunk" as the name suggests.

It has gained popularity in Finland, especially during the COVID-19 pandemic when people were asked to stay at home and avoid social gatherings. It is a way for people to relax and unwind at home while still following social distancing guidelines. While it may be a fun and harmless way to pass the time for some people, it is important to remember to always drink responsibly and to never drink and drive.
