Aberzombie core means: Aberzombie core is an aesthetic category that names the full visual and cultural package of brand-obsessed, aggressively preppy conformity: the polos, the khakis, the boat shoes, the suspiciously. It is internet-era slang, commonly seen on TikTok, Discord, Reddit or X. 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.
