Jabba-mouth
They won’t back down even when the whole world is screaming they're wrong. It’s like they have a pig in their head that won’t stop squealing.
''I’m not wrong! I saw it with my own eyes!', even though the evidence was right there.
''You’re all wrong, and I’m the only one who matters!', said to a group of people who had all agreed on something.
''You can’t prove me wrong, and if you try, I’ll yell louder!', because arguing is their favorite sport.
