Some type of
melon, I imagine. A
distribution of
NetHack I installed once had this set as the
default fruit name, leading to "My, that was a yummy yiffmelon" as well as tasty
potions of yiffmelon juice. At least yiffmelon is something I could probably
stomach, unlike
slime mold, the usual default.
My, that was a yummy slime mold
the fungus that grows on dungeon floors cold.
but yiffmelon be yet easier to swallow,
ere Arch-Lich comes and Demogorgon follows.
