With quick googling about KOSKELA BRO… which reads on the scoop, it must refer to KOSKELA BROTHERS, which are characters of Remedy’s game series Alan Wake. I also guess the start of the text is SPONSORED BY, bringing the whole message to SPONSORED BY KOSKELA BROTHERS. Yet another joke.
And for some reason, “kakka” is de facto word for excrement in Finnish, which is from the Uralic family.
It is very weird seeing it here, because it’s like THE word.
kakka is more like “poop” and the rougher word “shit” has a different word (paska[Learning about the homophone-y Pascal is always a knee-slapper])
