here are some Slovak words...
pojeb sa = fuck you (literally)
jebať = to fuck
kokot = dick (I would say that ,,kokot" is more rude)
piča = cunt (pronounced pitcha)
riť = ass
kurva = well, can have meaning as a slut or cunt too... also when something doesn't go well, you can shout ,,Kurva!"
hovno = shit
but as curses, we use mostly combination of kurva - piča - kokot like skurvena piča (fucking cunt) vyjebany kokot (literally i would say fucked up dick lol) etc.
