A person who is obsessed with Central and South American culture, although they themselves have little to no "natural" connection to that culture.

Persons with this trait will show a strong tendency to dine at Latin American restaurants, date Latin American men/women, and discuss global human rights struggles solely in terms of the citizens of Latin American countries. May attempt to co-opt Latin American culture as their own, or simply profess a strong communion with that culture.

It is important to note the distinction between persons who are simply sexually attracted to Latinos because of common facial features/skin tone, vs. true otacos, whose singular focus on all things Hispanic will also affect/impair other day-to-day judgments--for instance choosing to purchase a cheap gutrot mezcal if it is the most "authentic" option in an otherwise well-stocked liquor store.

Commonly occurs in people who grew up in Caucasian upper middle-class suburbs, in which a Hispanic working class was the second-largest demographic.

Apparently derived from the western use of the term otaku and the Mexican food item taco.
