People playing and hearing songs with looped beats and vulgar lyrics through a bass boosted sound system which costed them several months worth of minimum wage to pay for having it on their cars. They generally drive slowly through streets near beaches in order to exhibit their "fancy sound systems" while all the vulgarity plays repeatedly. I guess it's unique from this green-and-yellow country where I live.

I could also say wearing flip-flops and bermudas on a daily basis, or one of the highest usage and dependency of Meta's WhatsApp worldwide, or the country with the most welcome (often too nosy) people. Or, through a more positive lens, the richest land where crops easily grow when you sow something, the highest ecological diversity (especially plants, it's so common to find exotic plants here), the highest climate diversity (you can travel south to meet snow, then travel north/northeast to meet hot climates, without leaving the same country), etc.
