Spaghetti inheritance
[encountered among users of
object-oriented languages that use inheritance, such as
Smalltalk] A convoluted
class-subclass graph, often resulting from carelessly deriving subclasses from other classes just for the sake of reusing their code.
Coined in a (successful) attempt to discourage such practice, through guilt-by-association with
spaghetti code.
