Cinco de Mayo (seen - ko de ma - yo) literally means "The Fifth of May" and the day is celebrated because of the victory of the Mexicans against the French in Second Franco-Mexican War from 1861 to 1867. That is equal to about 6 years! What my OC is wearing on his head is known as a sombrero. The word "sombrero" literally means "hat." the thing worn on the OC's chest is known as a poncho. The poncho is commonly worn in Mexican and some South American cultures. They originated in 1000 B.C.E.
