Overriding builtins, functions or object methods means defining subs which replace them at runtime. Overloading is a related, overlapping, concept for operators and methods which it is enlightening to compare.

See perlsub, perldata on typeglobs, the perlobj family of docs, and the overload pragma. That is nowhere near an exhaustive list. You'll know a lot when you get comfortable with this question.
