Allusion
Allusion in a song One Thing - One Direction Shot me out of the sky You're my kryptonite You keep making me weak Yeah, frozen and can't breathe In the lyric there is "kryptonite" which i n popular culture, Kryptonite is a radioactive element that makes Superman weak whenever he’s exposed to it. And it has become a synonym of Achilles' heel , making it your fatal flaw that you sometimes can’t get away from. So in my opinion the lyrics tell of 'you' who was a weakness for them because 'you' is like a kryptonite, so when they saw 'you' they would be "frozen and can't breath".
