Cofiñu
Cofiñu is a colloquial Spanish term, primarily used in Guatemala, that refers to a person who is perceived as excessively concerned with appearances, mannerisms, and customs considered "high class" or foreign, often in an exaggerated or artificial way. The term carries a connotation of pretentiousness and may also imply a disconnect from local culture and traditions. It can also suggest someone who is trying too hard to fit in with a perceived elite or superior group, often adopting speech patterns, clothing, or behaviors that are not natural to them. The word often implies a lack of authenticity. The origin of the word is unclear.
