Rollo

Rollo is an informal word meaning personal problem. Here are some examples.

• No te metas en tantos rollos. Stay out of trouble. Avoid conflicts.
• A mí no me metas en tus rollos. Keep me out of it. This is your issue.
• Y ya después le conté un rollo acerca de mi ex novio. And then I told him about a big problem I had with my ex.

Es muy tu rollo

You can often use it where words like problema, bronca or pedo would also fit.

• Si andas con ella es muy tu rollo. It's your business if you go out with her. Don't come crying to me afterwards. I think it's a bad idea but Here you could also have said es muy tu problema, es muy tu bronca or (profanely) es muy tu pedo.

Sin malos rollos
