Squirtgun was formed by producer Mass Giorgini in 1994, and was made up of former members of his recently disbanded Rattail Grenadier. Squirtgun signed almost immediately to Lookout Records, with which Mass had already developed a steady relationship as a record producer.
Billie Joe Armstrong of Green Day, who co-produced The Riverdales with Mass, recommended Squirtgun to Jeff Saltzman, who was advising on the soundtrack for Mallrats, the then-upcoming film by Kevin Smith. The Squirtgun song "Social" was chosen as the opening song to the film, which has since become a cult classic.
Squirtgun's first full-length album, the eponymous Squirtgun, was released in 1995 on Lookout Records, and included the song "Social," in addition to a song called "Make it Up," which featured a guest vocal appearance by Mike Dirnt of Green Day.
