hardcore latina gangbangers. They usually have thin, arched, angry looking tattooed-on or penciled-on eyebrows, brown or dark red lip liner, 'Monroe', eyebrow and nose piercings, tats, Converse or Nikes, flannel shirts, lots of gold jewlrey (with their name and crosses), crunchy gelled or moussed hair either down or gelled in a high perfect ponytail either straight back or gelled in a design, and they go out with cholos.
A lot of regular mexican or puerto rican girls do the look but aren't cholas. A true chola is down for her barrio and is in a gang, and is as ruthless as a male gangbanger if not more. It is much more common to just look like a chola, and not act like a chola.
The chola style is common in southern California like east LA, San Diego, OC, and also NYC. In Miami they are called 'chongas'.
