Work The Room Meaning

(idiomatic, of a performer or public speaker) To interact with one's audience, taking cues from its reactions and adapting one's performance or words to elicit the audience's attention and enthusiasm.

Example:   As a campaigning politician, he really knew how to shake hands, kiss babies, and work the room.
1989, Alvin Klein, "Theatre: ‘Jerry's Girls,’ Revue, in East Windsor," New York Times, 26 Feb. (retrieved 3 July 2008):
  In show business parlance, Miss Hudson knows how to "work the room." Her comic turns are as rooted in vaudeville as her high-style wit is straight out of the smart supper club circuit.
