#in Finnish you just have to resort to saying a lot of cusses together

[ilthit]

On that best curse word tournament thing I always vote first on which is more satisfying to say and only second on meaning, but I have to say this one:

godverdeklotekleretyfuskutzooi (Dutch) /'ɣɔt.vər.də 'kloː.tə 'kleː.rə 'ti.fəs 'kʏt.zoːi/ a compound word that literally means, “God damn this nutsack cholera typhoid cunt mess”

kinda wins the bag on both AND gets points on persistence. You get a lot of bang for your buck there. By the time you're done your stubbed toe probably doesn't even hurt anymore.
