"vibe-coded" means: Adjective. Software written by giving an LLM a vague description and accepting whatever it produces. The opposite of careful spec-then-code.... This is a fairly neutral word with no inherent risk attached. There is no real cause for parental concern; it is descriptive vocabulary rather than something dangerous. If your child uses it, context will usually make the meaning clear. A brief, curious question about where they heard it is generally enough to know whether to follow up.
