Lol doesn't mean penis in Dutch, lul does.

Someone had some weird ideas on the Sweden one as well.

Fart = Speed (not the other way around)
Bump is not a word.
Kiss does actually mean pee.

Honorable mentions:
Kock = Chef
Slut = End
Sex = six (and sex)

¿Cool? I never hear it

Jerry means Jerry unless you pronounce like Gerry in Japan.

#3 - é um PEIDO, caralho que ta FODA !

culo means bum in spanish, but I dunno if cool means anything

Cool is bum in Catalan (cul) not in spanish (culo)
