"Armageddon It" is a song by English hard rock / glam metal band Def Leppard from their 1987 album Hysteria. It was released as a single in 1988 and went to No. 3 in the U.S. (their fourth U.S. Top Ten hit).The actual line of "Armageddon It" is meant to be a word play on the line "I'm A Gettin' It," thought up by the band during the recording sessions for the Hysteria album.
