"This Ain't A Scene, It's An Arms Race" was funny, like when Pete Wentz's penis circulated the internet." actually thats what the song was about. Pete Wentz and a ex of his sent dirty pics to each other and they broke up, and she put those pics of Wentz online and a critic wrote... something about it and horrible sh*t about Wentz, and Wentz wrote This Ain't A Scene, It's An Arms Race" because of that critice. so yeah. random Fall Out Boy fun fact!
Nice judgment there, Pete.
Wait, but that was a mean ex! PETE SHOULDA PUT HER DIRTY PICS UP IN RETALIATION
