cup of tea, one's(redirected from not one's cup of tea)
cup of tea, one's
Something that is in accord with one's liking or taste. For example, Quiz shows are just my cup of tea, or Baseball is not her cup of tea. The origin of this metaphorical expression has been lost, but the positive version-"he's my cup of tea"-has been used since the late 1800 and the negative- not one's cup of tea-since the 1920s.
