Shishi is like that.
Here, the term "shishi" means urine or to urinate. I thought it was a japanese term but I am not so sure because my wife (who is half chinese) grew up with that term as well from her chinese mother. In fact, when she was in kindergarten on the mainland, she wanted to go to the bathroom in school and told the teacher she wanted to go "shishi". The teacher did not know what she was talking about and she ended up peeing in her pants because of that misunderstanding. So in my mind I am wondering why a style would have that as part of its name.
