Moore told Great American Country about this song: "I always tell people, 'I don't know whether to apologize or say thank you after playing that song.' If you ask my mom, it's about a truck; that's what I told her. But if you ask Randy or Jeremy, it's probably about a rear end. I thought, 'I'm going to play that every night. It's hilarious.' I don't take myself too seriously and I thought it was a lot of fun and something different that I've never written anything like. It was a big song for us and we sold a lot of downloads of that. The struggle for a new artist is to have people recognize who you are. Instead of going, 'I like that song. Who does that?,' they go, 'Oh that's Justin Moore.' I think a song like 'Back That Thing Up' did it for us, where a middle-of-the-road song wouldn't have. We open our show with it."
