Phil explained that the title of this song refers to the basement of the house he grew up in (it was the third and lowest story of the house). He said that he would spend a lot of time alone there while his mom would disappear for three or four days at a time, explaining that this song is about the thoughts that would stir in his head as a result, especially in reference to his hatred for his stepfather.
According to Phil, the verses mostly represent his thoughts from the past, while the choruses mostly represent his thoughts regarding the future.
