Not Your Cup Of Tea
Meaning: Not what one likes or is interested in
Origin: The phrase “cup of tea” was first heard in Great Britain in the early twentieth century. Novelist Nancy Mitford first used the affirmative “my cup of tea” in her 1932 book, Christmas Pudding. The negative version came into popular use during World War II—there’s a lot more to not like during wartime than to like, natch–arriving stateside in Hal Boyle’s column Leaves from a War Correspondent’s Notebook.
Example: I know gory splatter films are not your cup of tea—actually, they’re a cup of tea many may choose to spit out into the sink.
