Ba (or 3) + name
This is the insult you throw at someone when they make a mistake so big, it feels like the universe just laughed at them. You add 'Ba' to their name like they're a joke that no one wants to hear.
Ba CoreJJ, you're like a broken phone that still thinks it's working.
Ba Chovy, you're so dumb, you think a match is a snack.
Ba Loke, you're like a dog who just ate a sock and thinks it's a treat.
