I like the French what (que or quoi), because I can't pronounce them and I like also how they sound. I especially love Qu'est-ce que c'est (que ca) ? What is it/that?
I like quite a few words from quite a few languages. Ciao stands out - also the entire Japanese spoken language because it's plain awesome and just so much different from the european languages.
I like the russian word for a string (i don't really know if that's the good english word, but it's lady's underwear where you can see almost her whole but) it's Ziepoesnetni and it really looks like dutch zie poes net niet. That is in english see pussy almost XD
