Two big fast food chains have beef... and I'm not talking about meat!

It all started, last week, when Wendy's tweeted out their 4 for $4 promotion, which includes a Jr. Bacon Cheeseburger, fries, four chicken nuggets and a drink.

Burger King decided to throw some shade back by sub-tweeting their own promotion which is 5 for $4 (BK throws in a cookie with theirs).

Oooo. Major shade. But WAIT! Because someone tweeted to Wendy's asking what they're going to fire back with and Wendy's simply replies with "edible food."

Yup, I think the burn marks are showing on Burger King's grill.

Who do you think wins this fast food war?
