Here's a breakdown of how it's used:
* Metropolitan: Refers to a large city or its surrounding area, often the main center of a region or country. It emphasizes the city's importance as a center of commerce, culture, and population.
* Metrosexual: Describes a man who is concerned with his appearance and follows trends associated with urban sophistication. The "metro" here implies a connection to the urban lifestyle and fashion trends found in big cities.
In both cases, "metro" signifies a connection to the city, its culture, and its perceived attributes.
