I cannot speak Finnish. But everybody knows which are the first words that one learns in a new language. Well, the word that some "artist" has drawn on the wall of this school is one of those. If you have doubts and even the drawing does not help, you can always use Google Translator!
The good news is, that is just snow that will melt away.
Update: I have just been informed that there is a mismatch between the drawing and the word. My bad.
