Baker Mayfield's clearly moving on from a drunken arrest he called "the biggest mistake of my life" ... 'cause he joked about the whole incident on a Fortnite stream earlier this week.
The Browns superstar took to Twitch to show off his gaming skills ... and while he was running with his avatar, he said, "Hopefully I’m running faster than I was in Arkansas right now!"
Of course, Baker was arrested back in Arkansas in February 2017 ... where he was infamously blasted by a cop who caught him immediately after he tried to run from being questioned.
Baker apologized shortly after the incident, saying, "I made the biggest mistake of my life by putting myself in this situation."
"The shame, guilt, and embarrassment I have felt over the past few days and continue to feel is something I would never wish upon anybody."
Clearly, Bake's ready to joke about the whole thing now ... broadcasting his Twitch stream to thousands of followers.
Wonder if Lincoln Riley is laughing??
