This mentions a form of playful teasing by close family members other than the parents. I wonder if this practice used to be more common in lots of cultures but has died out due to how disconnected many people have become from extended family. My wife grew up constantly seeing aunts, uncles, and cousins. Now we see my sister's family often, and my wife has a sort of playful teasing relationship with our nieces.
