not (really) (one's) thing
Not something one particularly enjoys or is good at. A: "Do you want to come with me to the concert this Saturday?" B: "No thanks, country isn't my thing." I'll give it a try, but car repair isn't really my thing.
it isn’t my, his, etc. ˈthingit is not something that you really enjoy or are interested in: I’m afraid pubs and clubs aren’t really my thing. I’d prefer to go to a restaurant with a few friends.
