Finnish noise rock band from Turku. Founded in October 1994.

The founding members were Ville Mäntynen (vocals), Raimo Pesonen (drums), Olli "Opa" Nikoskelainen (guitars) and Pirjo Kesseli (bass and backing vocals).
The idea of the band was to play "some noise". The songs were written by the whole band except the lyrics, which were written by Ville, leader of the band who's lyrics were highly influenced by decadent and absurd literature. The style of the band was in constant turmoil. The rough guitar walls of original line-up were replaced later with Paulina Ahokas' more violin-based sound, and eventually the band played very atmospheric and emotional music.
Mothers Against Sex Association quit in 2002 after the vocalist Ville Mäntynen died.
