Tõsised

Could you specify what “Tõsised” refers to? It could be a linguistic form in Estonian (the plural or descriptive form of tõsine meaning serious), a proper name for a band, a place, an organization, or something else. To ensure accuracy and neutrality, please indicate the intended subject. If you don’t have a specific referent, I can provide a concise, neutral short entry focusing on possible meanings and usage of the term.
