The high-tempo song includes elements of rapcore, hip hop, and pop punk, with Deryck Whibley, Dave Baksh and Steve Jocz sharing vocals. "The verses are really about what we do: growing up in the suburbs, going to parties and hanging out with our friends, and causing trouble. A lot of people say they relate to it," said Whibley. The song gets its name from the slang term for a swollen lip as result from being punched in the face. Rolling Stone magazine described the sound of the song "as if Sum 41 went from Blink-182 to Beastie Boys to Black Sabbath, all in one song."The song topped MTV's Total Request Live and MuchMusic's MuchMusic Countdown in the summer of 2001. In the original Canadian version, the music video combines with "Pain for Pleasure", a very short Iron Maiden-esque song that is the only metal song found on the album. The video was ranked at #75 on "MuchMusic's 100 Best Videos".
