Finnish Suicide

[HowardKennitby]

Derogatory colloquial Swedish term for someone who has effectively drunk themselves to death.

No actual derivation other than hearing it on an episode of 'Wallander' and asking a Swedish contact about it.

As a derogatory term, it goes with Mexican car wash, French letter, English disease, etc.
