derived from "Yeager" : the family name of the brothers Eren and Zeke from the anime "Attack on Titan" . The rebel factions from the military and the civilians which presents the persons who refuses to live inside the circled walls and wants to demolish all the world for the "Eldia Empire" eternity are called "Yeagerists".
All the people know that the Mexicans act like the "Eldians " in the real world by refusing the Donald's Trump walls , who -by the way- wants to save the world by stoping the tacos, tortillas, burritos and tequila's spread around the world .
You can't be a true Mexican if you are not a Yeagerist !
