 ", bassist Pete Wentz explained that the song refers to a romantic relationship in which the initial sentiments have perished, but both lovers continue to "sleep with each other" to appease their physical and mental desires.The title, "Thnks fr th Mmrs" is the words "thanks for the memories" after having been disemvowelled (the song title's removal of vowels comes as a facetious nod at Fall Out Boy's record company, who had asked them to shorten their often verbose song titles).The line that appears near the end of each chorus, "He tastes like you, only sweeter", is a line from the play and film "Closer".
