Cinco de Mayo fiestas are Americanization at its finest.

Americanization clue No. 1: Most Americans who plan to celebrate don’t even know what Cinco de Mayo honors. Sadly, Americans notoriously mix up Cinco de Mayo with Mexican Independence Day. They’re not even closely related—except for the Spanish words. Cinco de Mayo celebrates the Batalla de Puebla, when the Mexican Army defeated the French.

Americanization clue No. 2: Tacos, margaritas and mariachi bands basically sum up Mexican culture. Right.

Americanization clue No. 3: People in Mexico don’t celebrate it with the intensity that Americans do. Es verdad, Cinco de Mayo is a bigger deal among Mexican-Americans than it is for people south of the border. At least Americans know how to throw awesome themed parties. Here are a few:
