Slack Motherfucker

"Slack Motherfucker" is a song by American rock band Superchunk. It was the first single released from the band's debut, self-titled album (1990). The song was penned by vocalist and guitarist Mac McCaughan in reference to an indolent co-worker he had at the time. Credited to all four band members, it was the band's second single and first to be released under the name Superchunk.

Issued as a 7-inch single in April 1990, "Slack Motherfucker" rapidly became one of the band's best-known songs. It has been credited with popularizing the "slacker" stereotype, and as a blueprint for future indie rock music.
