Tough, mostly because of poverty and surviving (or not) public schools. Something to be said of poor, urban American youth and essentially no one else. Marked by resourcefulness, pragmaticism, and coldness. As a result of being shit on one too many times. A desirable trait. Can also be the result of an awful family life/childhood. See also hardcore
