The title of this song refers to a person who is such a good friend they would jump on a grenade for you. It is aimed towards the band's friend Chris Gutierrez (he's the "Chris" in the lyrics). Gutierrez was in the band Arma Angelus with Fall Out Boy bassist Pete Wentz. Because of the song, Chris is now known to fans as HeyChris. He has his own website at askheychris.com.
