Ah, yes, hello, I'm here to talk about my compadre Tenoch (pronounced more or less like Te-notch):
His name is obviously based on the name of the México-Tenochtitlan city, capital of the Mexica (best known as Aztec) empire, however, his name means Stone Prickly Pear (Te = Stone, Noch = Prickly Pear).
Ixtapoala doesn't seem to be an actual náhuatl word, however, I'm going to guess it's based on Iztapalapa, one of the Federal District of Mexico City's 16 boroughs. Iztapalapa means "Over the slab in the water".
Ollamaliztli (O-ya-mah-liz-tli) is the actual name of the ancient ball game from Mesoamerican cultures, and yes, it was used for more than just choosing the next human sacrifice, like solving political issues and even to determine who was the rightful owner of the lands, although it's still debated if the winners were the actual sacrifices, contrary to popular belief. This was because the Aztec thought that, by offering the blood of not only enemies but anyone deemed worthy, the sun would never extinguish, and by extension, they were making a favor to the world. The most popular variant of Ollamaliztli was the ball-hips one, where the players hit the ball with their hips, wearing only a special loincloth that was reinforced with leather, but some of them also wore special belts made of wicker or wood covered with leather for extra protection. The ball was made of solid rubber. There was a lot of balls and to this day, researchers don't know the 'official' size of the ball used in important ceremonial games, but evidence say that the ball probably had a diameter of 9 to 12 inches approximately, and it weighed 3 to 6 pounds. It was heavy and hard enough to cause serious injuries, like permanent contusions, nasty bruises that required to be cut opened, or some players were killed after the ball hit them on the face or stomach.
So yes, my compadre Tenoch might look silly to some people, but he is a badass cabrón.
