Nihongo Jōzu

If you look like foreigner and say any Japanese word in Japan, they will mostly respond with:

日本語(にほんご)上手(じょうず)ですね!
nihongo jōzudesune!

It's my hate-and-love faux-compliment with good intention. I hate it because my Japanese is still not good enough, I love it because Japanese people are so nice.
