I first saw the “Born in TX, Built by Texans” sticker on the back window of a Tundra while stuck in traffic in Houston.
I didn’t see the “Toyota Tundra” at the top.
Texans are very (very!) proud of where they’re from. Bright white t-shirts saying “Fuck y’all, I’m from Texas” are no longer a shock. The bold black lettering is usually large enough to be read from a distance.
So, knowing how Texans take pride in their heritage, and having overlooked the important reference to the make/model of the vehicle, I honestly read this sticker as another proud Texan declaring their family’s state of origin and publicly thanking their parents for getting it on.
