In Kotor, the twi'leks and rodians say "bona nai kachu" entirely too much. And now that I know some Huttese (and know that phrase means "you're in trouble now"), it bugs me a fair bit. They also talk about money ("moulee rah") too much. That's one good thing about Kotor II - the alien dialogue is much less repetitive. Whether it's all Huttese though, I'm not sure. We'll see when I play that game again!
