"Something in Your Mouth" is the second single released from Canadian rock band Nickelback's sixth studio album Dark Horse. The song was released as a digital download to the U.S. iTunes store on October 28, 2008. The song is much heavier than the first single "Gotta Be Somebody". It was officially released as the second single to rock radio only on December 15, 2008, similar to the release of "Animals" from their previous album All the Right Reasons.
"Something in Your Mouth" sees Nickelback returning to a hard rock sound with adult themed lyrics, similar to past hits "Animals" and "Figured You Out". The song is very fast paced with a prominent guitar riff, and describes a girl who teases the guys with suggestive dancing and sexual innuendos, with the line 'something in your mouth' being left open to various interpretations.
In an recent interview, Kroeger stated one of the guitar riffs had come to him while on tour. He recorded the riff onto his cellphone and sent it to the producer, Mutt Lange, who put a microphone up to his own cellphone and recorded the sent guitar riff. The cellphone recording is the exact same recording used on the album, never being re-recorded in a studio.
