An expression of teamwork, used when there are two people on a team, in any kind of event, against two or more people. Comes from the Xbox 360 game Army Of Two, where there are certain "Back To Back" sequences. During these sequences, the two characters go back to back and start shooting, in order to easily dispatch their enemies, who are usually terrorists. When this happens, sometimes one of the characters, Tyson Rios, shouts "Back To Back, Salem!", Salem being the last name of the other character. This term can be used anytime to imply teamwork.
During a paintball match, everyone except me and Payden were out. I heard him shout "Back To Back, Salem!", and we met up and continued to win the game against 4 other opponents.
