Yesterday, I was talking to one of my son's friend's parent, and she told me that her son went 'Goblin Mode' the other day and went in his room to 'Charge up', and asked me what it meant. I thought the kid was just being silly, but earlier today, my kid went 'Goblin Mode' too, and has been up in his room all day. Is this a new funny trend or something? I also found some 'memes' about going Goblin Mode, but I don't get it?
