That's true.

What a name!..

Yes, they're obviously not Scandinavian (where the name means male genitalia, plural).

Funfact: in the northern parts of Norway, calling a policeman a "horses penis" is not illegal, as that is a somewhat common thing to call another person. Yes, this was tested in court in 2008.

I have a theory that if a word is less than 5 letters long, it probably means male genitalia in a foreign language.

Interestingly enough, the number of <5 letter words in English is of the order of 10-15 000 [1], while the number of languages is 7000. Since most languages (I guess) have more than one word for male genitals, it is technically possible for all English <5 letter words to mean precisely that.

Funny coincidence, in some Spanish speaking countries kuka refers to the female genitalia. I have never heard kuka used in Swedish though. It does mean who in Finnish.
