In the opening chapter of Naked Lunch by William S. Burroughs, the first-person narrator is telling a story to an "advertising exec type fruit" on the New York subway, and in the middle of the story he goes on a digression:
"Ever notice how many expressions carry over from the queers to con men? Like 'raise', letting someone know you are in the same line?
"'Get the Paregoric Kid giving that mark the build up!'
"'Eager Beaver wooing him much too fast.'
