Noplace means: An informal American one-worder meaning 'nowhere' - compact, casual, and gets straight to the point. Where 'nowhere' feels slightly formal or literary, 'noplace' has a conversational, everyday. 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.
