In an interview with Alternative Press, Tyler Joseph said he wrote the song wanting to talk about what he was feeling and his frustrations, as opposed to something artistic and added that "I remember showing that song to some people and they said, 'I don't think you want to say that...'" Consequently, Josh Dun, the band's drummer, told him to "say it". Joseph also told Fuse in an interview that the song was "that song on the record where you kind of break that fourth wall and you can look into what it's like to really be a normal person in our position."
The music video for "Lane Boy" is slightly shorter than its album version, and shows Joseph walking with two men behind him in hazmat suits while Dun plays at a concert. Near the end of the video, Joseph joins Dun on stage and the crowd crouches down along with Joseph, afterwards jumping at the same time he does. The music video ends with Joseph performing a short dance and then bowing to the crowd.
