Perhaps its appropriate that the Thai word for stink is men. Its not pronounced exactly like the English word for adult males, but its pretty damn close. If you hear a Thai say something stinks, you'll hear "men".
The Thai word for a pleasant smell is hom. Ironically its the same word that Thai's use for onions. Today I told the maids "hom mai hom" (onions don't smell great), and they started laughing.
