From the bottom to the top

Asked by Billboard magazine how she came up with the song's title and imagery, Meghan replied: "You know how the bass guitar in a song is like its 'thickness,' the 'bottom'? I kind of related a body to that."

The song depicts the "ideal" skinny body type as overrated and promotes body acceptance by celebrating men and women of all sizes and shapes with lyrics such as "Every inch of you is perfect from the bottom to the top" and “It's pretty clear I ain't no size 2, but I can shake it, shake it like I'm supposed to do". Trainor says, "I wrote this song because I myself struggle with this concept of self-acceptance. It was written from a real place so I’m glad that other people can relate to it." Though it has been suggested that the song is a feminist anthem, Trainor has insisted that she didn't set out to write a feminist anthem, rather a universal message to appreciate your "booty".
