What do Texans call their mom?

I'm curious, have you ever heard of the unique nickname Texans give to their mothers? It's a fascinating cultural quirk that I've come across in my travels. Can you shed some light on this tradition? What exactly do Texans call their moms, and is there a specific reason behind this endearing term? I'm eager to learn more about this regional dialect and how it reflects the culture and identity of the Lone Star State.
