Chipotle is adding a new word to your vocabulary during the NBA Finals.

It's called "freeting," which means to tweet Chipotle during the series every time an announcer says the word "free" on-air during a game.

Here's how the deal works: if you're watching the NBA Finals and hear the word "free," Chipotle will tweet a unique keyword that unlocks up to 500 free entrees during the first half of the game. The company even adds there could be up to 1,000 free entrees during the second half of each game.

The first 500 to text the unique code to 888222 will get a code for their free offer.
