'Shit' is 'paska' in Finnish. 'Son of a bitch' would be 'nartun penikka', but no one ever says that, it sounds more like joking than insulting. You can say 'kusipää' ('piss head'), 'vittupää' ('cunt head') or 'paskiainen' ('douchebag') instead. Let's not forget the everuseful f-word! :) It's 'vittu' in Finnish. You can use it also in a pattern 'f*cking xxx' by saying 'vitun xxx'. Have a good time swearing in Finnish! ;)

Shit = ”paska” I'm not sure about son of a bitch though, it's not the sort of a thing that we say here... But ”paskiainen” is one option, one could also say ”kusipää”.

paskiainen, paska ^^ i just translated so not sure
