Mothercreep is a song off of FKA twigs' third EP, MXLL155X. The song was the only song off the EP that was not included in the short EP movie.
Speaking to Complex magazine, Twigs described this as an "apology." She said it's about "the time when you realize that when you were 15, you didn't know everything." The singer added that it's also about "understanding - through becoming the alpha female in my household now - how the other alpha female in my life did things."
