A track from Twisted Sister's breakthrough third album Stay Hungry
, the title is an initialism for "Sick Mother F--ker."
By this time, the band had been around since 1973, and while most of their audience discovered the band through their MTV hits "We're Not Gonna Take It
" and "I Wanna Rock
," they had a loyal following from their years slogging it out in clubs. Introducing this song at concerts when Twisted Sister was at the peak of their powers, lead singer (and songwriter) Dee Snider
said: "This is a song that will probably never make it to the radio, and it's a song that not everybody's going to like. It's a song for the real friends of Twisted Sister - the people who have been there through [1983 album] You Can't Stop Rock 'N' Roll
, back through [1982 album] Under The Blade
. This one is for you."
