What's the meaning

of breaking my balls here?

"I get that it must really suck to be a kid growing up in a small condo. I would tolerate it happening a couple of times per week, or on rainy days. It is really getting to me because it is happening every day(he's talking about the kids playing in the hallway outside his apartment). Plus, the condo has a great backyard with a swimming pool, a small park, a volleyball net etc... There is also a great bike trail right next door, and a huge park three blocks away. The kids have options that do not involve breaking my balls."

Thanks a million!
