Rupeon
Rupeon to joke with each other or play fight with young minds to eachother. Which dose not fit perfect for the teens or parents, yet sort of a phenomenon because animals see no issues with it, yet no excuse because everybody needs to be safe, yet know self defense. Boys will be boys as long as it's not bullying. Yet emotions know all for young to adult years yet change naturally.
Him & his friends would Rupeon, to challenge each other as young teens in horse play like young loyal puppies do.
