Whataburger Trolls In-N-Out with a Billboard the Size of Texas

Don't mess with Texas, especially if you love In-N-Out. The rivalry between the Californian burger joint famous for Animal Style and the Lone Star State's very own Whataburger continues to grow as things like this very wrong map of each state's best fast food chain. The map from Business Insider just about broke the internet as outraged Texans rallied against In-N-Out. Today, however, there's one more log on the fire between Whataburger and In-N-Out, and it all comes down to a billboard.

The first photos of this Whataburger billboard looming over an In-N-Out in San Marcos circulated in August, but it didn't make waves until recently when another photo was tweeted.

Here's the original from August.

And the most recent photo set.

The reactions from Twitter users were even better, igniting some serious state pride in Texans.

In San Marcos there's a In-N-Out and right next to it there's a giant billboard telling you to head to the nearest Whataburger.

What do you think of the proclaimed 'power move' from Whataburger? It definitely seems like this fits in with Whataburger's personality, something that always keeps us grinning from ear to ear.
