not my cup of tea

Not my cup of tea is another way of saying you dont like something very much, but more of your own opinion not necessarily that you hate the concept of it or are judging others for liking it. Something not being your cup of tea can be referring to anything you dont favor such as an item, a personal fashion sense or style, a type of haircut, a food or drink item, an activity, or even a type of person that just doesnt interest you.
