Why is "Chichimec" trending?

Wikipedia Overview

Chichimeca is the name that the Nahua peoples of Mexico generically applied to nomadic and semi-nomadic peoples who were established in present-day Bajío region of Mexico. Chichimeca carried the same meaning as the Roman term "barbarian" that described Germanic tribes. The name, with its pejorative sense, was adopted by the Spanish Empire. "For the Spanish, the Chichimecas were a wild, nomadic people who lived north of the Valley of Mexico. They had no fixed dwelling places, lived by hunting, wore little clothing and fiercely resisted foreign intrusion into their territory, which happened to contain silver mines the Spanish wished to exploit." Chichimeca was used as a broad and generalizing term by outsiders, writing, "[it] was used by both Spanish and Nahuatl speakers to refer collectively to many different people who exhibited a wide range of cultural development from hunter-gatherers to sedentary agriculturalists with sophisticated political organizations." They practiced animal sacrifice, and they were feared for their expertise and brutality in war.
