• This is the breakthrough cut for OG Maco. It catapulted the Atlanta rapper into relative stardom after a number of users of the video media app Vine uploaded content with the song, due to its amusing message.
• Maco freestyled the rhymes when he was drunk and angry with his engineer. The rapper told Complex magazine: "He was supposed to make me ten beats that day or something like that, and I came back and this lazy ass nigga didn't have no damn beats. So I went in [to record], put on some headphones, and told him, 'Play some s--t, press record."
• The original version of the song featured the Atlanta rapper Key!, but he later removed himself from the cut. Maco explained: "When the song was made it was just some random s--t that happened in my house. It was never originally me and Key!. Early on when we were making Give Em Hell, I told him he might want to hop on it because the song is going to go. He was like, 'Okay, whatever,' and he got on the song."
  
  "I shot two different videos [for "U Guessed It"]," he continued. "When I shot the first video, Key! happened to walk past the video shoot. I called him and told him to come, and he walked past it. So I asked him, 'Are you trying to be in it?' and he said, 'No, I don't want to be in your video.' I was like 'Cool, it's whatever.' I wasn't offended. It's just Key!. I was like f--k it."
  
  Maco added that he was still cool with Key! - as the rapper hosted his video release party.
• The official remix to the song, featuring 2 Chainz, was released on September 26, 2014.
