Everything is bigger in Texas. I'm not exactly sure what they mean by that, but who am I to argue? Do they mean egos? Could they mean armadillos? Doesn't Texas have the highest population of overweight people in the US? Could that be the meaning behind the phrase? Chances are none of these are the real driving force behind these words, so if you want to find out the true meaning maybe you should just get this 100% preshrunk cotton t-shirt to use as a conversation starter and I'm sure an answer will pop up.
