When i was younger i had a bedroom with a small closet sized bathroom and a friend that was always going in there and taking rancid shits when he'd come over. A few times I came home from class to find out he'd gotten suspended for the day and just hidden at my house cause he didn't want his parents to find out he'd been kicked out again.
One day when he was coming over (We'd known each other long enough that he'd just walk in the house) I hid in my bathroom and found some brown zombie kit makeup my older brother had left. I painted my face and arms up, grabbed a mall ninja sword from my cousins room, and waited. When he opened the door I sprang out shouting as loud as I could covered in brown halloween makeup with a conan the barbarian sword. His brother got a photo of me holding the sword to his brothers head making a derp face. I don't know if this is technically black face. But they love to act like it is and pretend they're gonna show the world.
idk man, 9th/10th grade was a weird time. So was my bathroom.
