The need or want to eat certain foods because of the pleasure you receive from crapping it out. For example, spicy food because it burns your
asshole or garlicky beans because you can kill
trees with your gas and peel the
paint off the walls when you blow up your bathroom.
Example 1: I have a real crappetite for that ghost pepper sauce, there's no
better butthole burn!
Example 2: I have a real crappetite for baby
food because how it eats isn't as important as how it craps.
