(the) street

   prostitution

   The place where customers are picked up:

    'You're the only person who can save us.' 'How?' 'Why, the street, of course.' (Londres, 1928, in translation)

   A street-walker, street-corner girl, or street girl is a prostitute:

    The modern equivalents of the old-time disorderly house and of the street walker. (Lavine, 1930)

    I guess you must have taken up with the wrong street-corner girl the last time you were in Baton Rouge. (King, 1996)

    ... her wretched career from housewife to street girl. (S. Green, 1979)

   On the street(s) is to be engaged in prostitution:

    She fell in love with Mary Jack's pimp, who put her on the street. (L. Armstrong, 1955)

   The American street tricking is finding customers as a prostitute on the street:

    This old campaigner we call Mabel the Monster, been street trickin' must be ten years now. (Diehl, 1978)
