The phrase "Anyone for tennis?" (also given as "Tennis, anyone?") is an English language idiom primarily of the 20th century. The phrase is used to invoke a stereotype of shallow, leisured, upper-class toffs (tennis is often seen as a posh game for the rich, with courts popular at country clubs and private estates). It's a stereotypical entrance or exit line given to a young man of this class in a superficial drawing-room comedy. — Stephan Humphrey Bogart, Bogart: In Search of My Father
