In Stockholm public library catalog users can tag content. And here I found one of the finest tags:

jobbig-men-bra

Loosely translated: strenuous but good
Jobbig is a bit hard to translate, the closest I can came was strenuous, it could also be translated with tough.

The tag is used to describe content like the film Dancer in the dark by Lars von Trier and La Haine by Mathieu Kassovitz. I think the tag is very accurate in relation to these films ;-)

Another feature in the catalog is that you can report abuse in tags. This is probably a thing that many folksonomies must incorporate to avoid spam.

Unfortunate the authors of the tags are not displayed. I don’t know if its there is a legal problem with showing public library users in Sweden.

What a great tag: JOBBIG-MEN-BRA
