Okay, a little example dialog.

- Слушай, ты знал, что Вселенная бесконечна?
- Да мне до одного места!

Here's a rather rude way to say that you don't care beans about something. And by одного места you really mean one of the "embarrasing" part of human's body like an ass (usually exactly this part) or something else. Yeah, and we tend to replace those parts of body with the phrase одно место, it's common to do like that
