Anyway, I went on walking home, thinking about the movie, and then suddenly wishing I had some company. Greasers can't walk alone too much or they'll get jumped, or someone will come by and scream "Greaser!" at them, which doesn't make you feel too hot, if you know what I mean. —The Outsiders,
S. E. Hinton
