La letra aborda una relación romántica inestable causada por los cambios de humor de una pareja. Estos cambios de humor podemos observarlo en el estribillo cuando dice que el caliente y ahora frio, también podemos verlo en el video de la canción que es un casamiento y el novio duda en decir que si.
You change your mind Like a girl changes clothes Yeah you, PMS Like a bitch I would know And you always think Always speak Correctively I should know That you\\\'re no good for me Cause you\\\'re hot then you\\\'re cold You\\\'re yes then you\\\'re no You\\\'re in and you\\\'re out You\\\'re up and you\\\'re down You\\\'re wrong when it\\\'s right It\\\'s black and it\\\'s white We fight, we break up We kiss, we make up You, You don\\\'t really want to stay, no You, but you don\\\'t really want to go-o You\\\'re hot then you\\\'re cold You\\\'re yes then you\\\'re no You\\\'re in and you\\\'re out You\\\'re up and you\\\'re down We used to be Just like twins So in sync The same energy Now\\\'s a dead battery Used to laugh bout nothing Now your plain boring I should know that you\\\'re not gonna change Someone call the doctor Got a case of a love bi-polar Stuck on a roller coaster Can\\\'t get off this ride You change your mind Like a girl changes clothes
