Aberzombie pilled means: Aberzombie pilled describes someone who has fully swallowed the preppy conformist worldview - not just wearing the clothes but genuinely believing that social status, brand loyalty, and group. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. 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.
