OK, I know this is not the right place to do this, but my curiosity
is killing me. Linux's fortune cookie program gave me this from it's
translate-me section:

"sillema sillema nika su"

What does it mean? Or at least, which language is it in?

Google was no help (it only redirected me to further quotes of the
thing from the same source).

Sillema I gather is also a Dutch surname?

nika su is very possibly an expression in some Slavic tongue.

Any further hints?

Yours curiously,
