knulla in swedish

edit: Just saw it was already posted...

And "I wanna fuck you hard" is

Jag vill knulla dig hårt.

to fuck, fucking

in german: ficken
in greek: gamisi

in hebrew: lezayen
russian : pihnut,otebat

that's a great try :)

I think you mean: Jag vill knulla dig hårt = I want to fuck you hard
:pimp

"Fornicar" in Spanish means sex. It's the "medical" terminology for fuck. For the slang or obscene terminology it's

Chinga - fuck
Chingar - to fuck
Chingo - I fuck

Chinga Tu = Fuck You :)

Chinga tu madre - fuck your mother

Oh by the way, sorry I don't have Spanish keyboard, there should be an accent mark over the "u" in "tu" in both instances.
