shit, feces, excrement
糞 centers on solid bodily waste: feces or excrement. The vulgar sense 'shit' is a direct, informal application of that same meaning.
糞 combines 米 (rice) with 異 (unusual, different), likely suggesting the transformation of food into waste. The exact historical development is uncertain.
Rice 米 goes through an unusual 異 process in the body and comes out as something very different: feces.
For フン, imagine the sound of something heavy dropping: 'fun!' The fun sound cues フン while the rice turns into waste.
