Finnish

Someone or something that has relation to or origin from Finland.

The main language of Finland. Finno-Ugric.
One of the hardest and weirdest languages on Earth.
Contains the best swearwords; saatana, helvetti, kyrpä and essentially perkele.
The tone may sound angry and irritated for tourists, but actually Finnish people are quite nice.
Has some really long words, like "epäjärjestelmällisyydessänsäkään" and "metsämarjatäysmehutiivistepurkki". (Sorry, can't translate them, but they really are accurate Finnish words.)

Finnish people are predominantly blonde, Finland has the highest proportion of natural blondes in the world. A study by experts in Germany suggests people with blonde hair are an endangered species and will become extinct by 2202. The problem is that blonde hair is caused by a recessive gene. Researchers predict the last truly natural blonde will be born in Finland.

Nearly completely resistant to cold, Finnish people tower over the other Nordic people as the superior race, born with superhuman reflexes to play ice hockey and wrestle bears to gather food for their families.
The Finnish people are not fazed by aggressions by anyone, they do not care.
A notable example of this is them saying "Fu*k you" to the Russian invasion and kicking their asses with a fraction of their military strength in men and close to no combat gear.
Finnish girls often have blonde hair and crystal blue eyes, making them one of the most desirable girls out there.

To make something become from Finland.
