shaming when young

I saw a third-grader today, whose name shall remain anonymous. He was at the library, but had some strange bruising along his neck and near an eye. Apparently, he friends decided to marker him when asleep -- shaming. It was mostly cleaned, but there were odd circle patterns on his neck and 4-day old healing yellow on his eyes... which I was told were flowers.
He planned on revenge via his mother's make up. I suggested to him to take a photo of his work.

Shaming; to physically humiliate and embarrass a person through body masking, positions, physical change -- not the same as hazing requiring the person to consciously participate.
