Chris Pratt says he takes FULL RESPONSIBILITY for torching Aaron Rodgers' steak on a couples trip earlier this month -- falling on the sword in the biggest celebrity meat story since "Kim Kardashian, Superstar."
Turns out Pratt's wife, Anna Faris, is tight with Aaron's lady, Olivia Munn ... and the foursome went on a fun outdoorsy vacation together last week. And everything was cool ... until dinner.
When the guys charred the steak, Olivia man-shamed the duo on social media. Now, Pratt's doing what any superhero would ... saving a friend.
But more importantly ... sounds like the guys had a good time together (perhaps a bromance is brewing?) ... and Pratt says the Packers QB is quite the outdoorsman.
Fingers crossed this one lasts longer than McConaughey/Armstrong.
