  • Wow. I looked all over the place for a definition that would merit John's using this term as a synonym for "gunk," and finally had to go look it up in the OED.

    To me, "mung" is just a kind of plant that you get mung bean sprouts from. I kind of like them, even though they're really not made of anything. It's like eating crispy air, though not as crispy air as rice cakes.

  • Not sure what you're asking... 'is "chicken feed" close to gunk,' perhaps? If so, I'd say no. I think of bits of dried corn when I think of chicken feed. Or nice crunchy beetles.
