The wiener wars between Burger King and 7/11 have just kicked off.

On Tuesday, the fast food burger chain unveiled its hot dogs, called Grilled Dogs, to the world. But 7/11 isn’t just sitting back and letting it happen. In a tweet, Burger King announced, quite simply, “Grilled Dogs have arrived. .”

The franchise has been hyping the new product in recent days. In fact, Fortune had the opportunity to taste test the wieners earlier in February. There are two hot dog varieties, a hot dog with relish, chopped onions, ketchup, and mustard as well as a chili cheese dog.

7/11 retorted on Twitter: “.@BurgerKing – In the great hot dog war, there can only be one weiner.”

But that isn’t all. The brand has unleashed a barrage of tweets against Burger King’s new offering:

Notably, it doesn’t appear that Burger King has responded to 7/11’s repeated barbs at the addition of hot dogs to its menu.

Burger King’s hot dogs have been released to the U.S. after first being tested in five cities last year, including Salt Lake City, Memphis, Baltimore, Detroit, and Kansas City.

In other fast food news, McDonald’s appears to be changing its McPick 2 for $2 deal, as Fortune wrote about Tuesday.

Fortune has reached out to Burger King for comment, and we will update this story once we hear back.
