Sur 13 is another name for the Sureños (Spanish for "Southerners"), a group of Mexican American street gangs with its origins in the oldest barrios of Southern California. Sur 13 also stands for "Southern United Raza." Raza is Spanish for "Race." The Number 13 stands for the letter "M," paying homage to the Mexican Mafia Aka La Eme.

A sur rat is a bitch made nigga, affiliated with or a part of the gang Surenos. They eat mens ass whether it's a male or female doing so. They tend to love sucking limp dick and cannot get their own dick to an erect position. Because of this they have very few female members who aren't transgender or lesbian due to all Surenos having a small, limp, dick. Also most Surenos commonly look like the skin between a mans asshole and ballsac so their pretty easy to spot.
Ewwwwwww, a Sur Rat!(Sureño)
