If you’re with a Korean provider, make sure you tell her, “I know the difference between 된장 (“Den Jang” which means “Bean Paste” which is used to make tofu soup) and 똥.” (“Ddong” which means a pile of shit).
Korean bean paste looks like shit. It’s used to make Tofu soup. So this quote means, “I know the difference between the two so don’t f*ck with me.” lol.
