  Title: Legal name
  Passage: Legal name is the name that identifies a person for legal, administrative and other official purposes.  A person's first legal name generally is the name of the person that was given for the purpose of registration of the birth and which then appears on a birth certificate (see "birth name"), but may change subsequently.  Most jurisdictions require the use of a legal name for all legal and administrative purposes, and some jurisdictions permit or require a name change to be recorded at marriage.  The legal name may need to be used on various government issued documents (e.g., a court order).  The term is also used when an individual changes his/her first or full name, typically after reaching a certain legal age (usually eighteen or over, though it can be as low as fourteen in several European nations).
  Title: My Girlfriend (Relient K song)
  Passage: "My Girlfriend" is a song by the Christian rock band Relient K, released on their self-titled first album.  The song originally appeared as "Marilyn Manson Ate My Girlfriend" on the band's demo album, "All Work and No Play".  The song is about Marilyn Manson eating Matt Thiessen's girlfriend.  Thiessen wrote this song when he was 15 years old.  Thiessen has said that he wrote it because of a female friend, who lived eight hours away in Pennsylvania, who he would talk to about many things including spiritual matters such as where God was taking them in the future.  His friend would later turn from Christian music to Nine Inch Nails and Marilyn Manson.  In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.  Thiessen would later state "She felt that Christianity was stupid and just this big hypocrisy.  Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson."
