Well this is fun;
“Güeros is the plural form of the Mexican Spanish term güero, which literally means a person with fair skin and/or blond hair.
While originally derived from the word huero (meaning “empty” or referring to an unhatched egg), the term has evolved into a common, often affectionate descriptor in Mexico. Key nuances include:
Not Just for Blondes: It is frequently used for anyone with a lighter complexion, regardless of hair color, and can even be applied playfully to darker-skinned individuals as a term of endearment or familiarity.
Social Function: Vendors and locals often use güero (or the diminutive güerito/güerita) as a friendly greeting or sales tactic to create warmth, rather than a strict racial or physical classification.
Distinction from Gringo: Unlike gringo, which specifically refers to Americans or foreigners, güero is primarily a physical description that can apply to Mexican nationals with light features.
