 The song is about truck drivers and "blue-collar workers" using methamphetamines.The band's Woodstock 1994 performance of the song was particularly notable, with Claypool beginning a bass rendition of the Star Spangled Banner in homage to Jimi Hendrix's guitar performance of the national anthem decades before, but eventually apologizing to the crowd by saying "Sorry, I had to do it" and returning to the song.As of 2015, it is Primus's second most-performed song live.
