"Out for Blood" is a song by Canadian rock band Sum 41, written by Deryck Whibley and Mike Green.^[3] It was released as the lead single from the album Order in Decline on April 24, 2019.^[4]

The video was directed by Lee Levin and features ^{[citation needed]} several misfit people in their day to day jobs with situations where someone frustrates them; like getting rejected by a door bouncer, handing out mail and given an empty coffee cup in an office (realising his job is so unfulfilling), having someone walking through a just cleaned floor, doing a tattoo in an undesired region of a client and having a patron with her young daughter in a roadhouse-style restaurant rejecting served food. After the first chorus, they all lash out in anger. The fans all arrive at the band's performance, turning it into a concert and during the guitar solo, they get into hyper violent moshing, ending up with them all smiling, showing off their bleeding facial cuts by the end.^{[citation needed]}
