I prefer to say that code is like a Rube Goldberg machine.
While it technically does the job, it is over complicated making it hard to add new features and easy to introduce bugs.
If we rush to add a new feature, it will be like adding another crazy contraption making it even harder to make changes to in the future.
But if we take a little time to clean up the code, it will be like a well oiled machine giving us a solid foundation to build new functionality on top of.
Another interesting point is that although Rube Goldberg machines are complicated, they are extremely decoupled from start to finish... I've never thought of decoupling code in a negative way before...
