Around here, most of the refs with whom I work use the term "wreck ball" just for men's leagues. Kids leagues are not usually put in the same category at all. It's very unusual to find kids who are angry at life because 10 or 20 years ago they were cut from their HS team and, of course, it was because the coach played favorites and life just isn't fair so now they have something to prove, including taking out the aggressions that built up that day at work and at home onto a basketball court.
Or something like that.
