- Modern Spanish: Gained emotional and social meaning
Cultural Interpretations
- Spain: Neutral descriptor, sometimes blunt
- Latin America: Often affectionate, especially as a nickname
- Urban cultures: Friendly slang rather than literal description
In many Spanish-speaking communities, flaco became less about appearance and more about connection and familiarity.
