S.mouse (born Shwayne Booth Jr.) is a U.S. rap artist who released the biggest selling hip-hop single of all time, "Slap My Elbow". Although the kid-friendly song was a huge success, S.mouse craves the recognition of his edgier peers. Trying to reinvent himself, he defies his record company by releasing the home-made song, 'Poo on You'. This song, and the corresponding music video of him pooping on a police car, creates a cult following ? but also leads to his placement under house arrest.
