These days, it's hard to throw a lime wedge without hitting a celebrity-endorsed tequila.

Musicians, actors, Instagram-famous models... it seems like everybody's got one.

But only one tequila is backed by the Rock. 

And, more importantly, the actor wants to buy you guacamole for Cinco de Mayo.

Guac on the Rock is an initiative by Dwayne Johnson and his tequila brand, Teremana, that runs the entire month of May. They will reimburse you for your guacamole when you purchase it alongside any Teremana tequila cocktail. The program is meant to help restaurants and workers, while also giving you some free guac, so grab a chip and do your part.

Also, the timing is two fold, as Johnson's birthday is May 2. Sure, we'd rather have received an invite to his birthday party, but this isn't a bad way to celebrate.

Here's how it works:

• First, be at least 21 years old. Then, find a participating restaurant near you, which is easy to do via guacontherock.com.
• Between May 1 and May 31, buy a Teremana tequila cocktail and some guacamole at one of those said restaurants. Then upload your itemized receipt via the website by June 5.
• Once approved, funds will be transferred directly into your Venmo account. You'll get up to $10 for a single guacamole order, with a total cap at $1 million nationwide.

Look, you've never needed a reason to drink tequila and eat guacamole. And you don't need one now. But it's hard to turn down free guac.

And it's nice to see that Fast & Furious money going to a good cause.
