Toshy carries two divergent meanings depending on region. In Scottish dialect it means neat, tidy, or clean — a positive quality of orderliness. In British slang more broadly it means rubbishy, trashy, or worthless — the opposite valence entirely. The British slang sense is more widely applicable in contemporary use; the Scottish sense is dialectal and somewhat archaic. The coexistence of two almost opposite meanings in the same word is a good reminder to check regional context before assuming you've understood.
