Macaulayism means: The act of westernization of upper class Indians using educational reform.. It is mainly Indian English and may not be understood outside that context. It is generally derogatory or offensive; worth a quiet word about how it lands on the person being described. It is an education-system term, so usage is institutional and routine. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
