"Lump" is a song by alternative rock band the Presidents of the United States of America. It was released in 1995 and featured on their self-titled debut album (1995). The song reached number one on the US Billboard Modern Rock Tracks chart same year. Composer Chris Ballew said that the lyrics combined his own history of having a benign tumor in the head with a vision he had of a woman in a swamp, while employing the word "lump" because Ballew was fond of it. The musical part was described by Ballew as him "trying to write a Buzzcocks song". Ballew considers it his favorite composition.
