Summertime Blues

We have our own rituals in the end of half of a school year. One horrible is a summer hymn. But now someone has written new words with slang orientation (language outside of conventional usage, little bit borrowed with Swedish).

Ja kaiken uusiks duunaa
noi säteet suulperin.
[...]
Taas nurtsit vihannoivat
ja hiffaat fogelin.

Glad to hears, `couse
however, Finish is so rigid language with as almost as nazi connotations.
