Trece when used with Sur (south) means gangster... so Sur Trece is Southside Gangster.
Literally means 13 though. hence the gang affiliation. Mexican Mob. MS13. and etc.
Not the same as a Cholo... because a Cholo
is NOT a gangster. They are just latino thugs
(thugs = ppl all about themselves not the set).
Sur Trece usually wear kahkis with a button up that only has the top button buttoned (2 is the Trece is white, very rare ime)
hey don't go lookin like a cholo in front of the Treces over there they don't think twice about killing Levas not down for the Raza.
