The last line of the song, "Twelve majestic lies," refers to an alleged government conspiracy group called Majesty 12, who supposedly cover up UFO and Alien activity.
Tom Delonge told Mic
in 2016: "The very last line of that song references this urban legend in UFO folklore called Majestic 12; these documents that got leaked in the '80s that described an entire organization of top-level scientists, military people and intelligence officials that manage the information of this phenomenon. I put the name in that song, and the irony now is that I'm dealing with people from the modern version of whatever that group is called. It's a big deal."
