The song's lyrics express (over) confidence that his personal level of sexiness makes him too sexy for numerous things, most notably his shirt ("so sexy it hurts").
The list also includes "my love (love's going to leave me)", "Milan, New York, and Japan", "your party (no way I'm disco dancing)", "my car (too sexy by far)", "my hat (what d'you think about that?
)", "my cat (poor pussy... poor pussycat)", and the song itself: "...and I'm too sexy for this song", at which point the song abruptly ends.
The song samples the guitar riff from Jimi Hendrix's 1967 song "Third Stone From the Sun".
