Finnish Itsemurhayksiö (lit. suicide one-room residence)A small and depressing apartment.

Yes, I know compound nouns are cheating, but this is definitely one of my favourite words. Colloquial, tongue-in-cheek description of a one-room apartment that is really small, and meant for living alone (very alone). The fact that it's so small, which makes it impossible to invite in any company, makes it perfect for being alone and getting depressed. Usually an apartment where students might move in right after moving out, and usually apartments like these were built in student areas due to a lack of apartments available after a sudden increase in the number of students.
