What Does OOP Mean in a Text?

OOP means "Out Of Print," "Object-Oriented Programming," "Out Of Place," or "D'oh!"

Here is some more information about each meaning:

Out Of Print

OOP is routinely used on online selling sites, such as eBay, to mean "Out Of Print." In this context, it indicates that the item (usually a book or a record) is no longer being manufactured and suggests there is only a limited number available.

Object-Oriented Programming

Most commonly used programming languages (e.g., Java, C++, C#, Python, PHP, JavaScript, Ruby) use "Object-Oriented Programming." These languages all use "objects," which can access or modify associated objects or data fields. In other words, there is routine interaction between objects to provide the program logic.

Out Of Place

OOP can also mean "Out Of Place." In this context, it is similar to AWKS (Awkward).


When used to mean "D'oh!" OOP is an interjection, typically uttered on realization that someone (usually the speaker or sender) has made a mistake. (OOP is not a word you want to hear from your tandem skydiving instructor, surgeon or pilot!)
