Grisch refers to a Swedish slang term describing a certain stylish, often exclusive-leaning aesthetic and attitude. It can imply a vibe of refined, city-smart dress and behavior that signals affluence or trendiness, sometimes with a self-aware, ironic twist. The exact nuance can vary by context and region, and different sources describe slightly different shades—from a “pappastil” or mature street style to a broader lifestyle associated with luxury aesthetics. If you want, I can tailor the explanation to a particular usage (e.g., casual conversation, social media slang, or academic discussion) or provide examples in Swedish with translations.
