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.
