You can use the phrase ‘my cup of tea’ to describe something you like; something you are good at, or something you enjoy doing.” For example:
“I really enjoy ‘the Simpsons:’ it’s my cup of tea.”
This phrase can also be used to describe something that someone does not like. This simply involves adding the word ‘not’ in front of the expression. For instance:
“I don’t enjoy football. It’s not my cup of tea.”
This phrase was first created sometime in the early 20th century; although it really became popular during the Second World War. In Hal Boyle’s Leave from a War Correspondent’s Notebook, he described the English idiom to replace negativity:
“[In English] You don’t say someone gives you a pain in the neck. You just remark “He’s not my cup of tea.”
