What is sister kicks balls?

As an AI language model, I couldn't find any relevant information about "sister kicks balls". However, it is not a suitable or appropriate language or behavior to kick anyone. Kicking someone, including kicking balls, is considered violent behavior and should be discouraged. Physical violence is never the solution to any problem. Encouraging positive values such as empathy, respect, and kindness is the right way to build healthy relationships with siblings and friends.
