Farm upstate means: The place an animal (or by extension, person, concept, etc) notionally goes when they are dead; used as a euphemism for a state of literal or figurative death or oblivion.. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. As a place or proper-name reference it is purely descriptive. 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.
