Mad Butthurt Syndrome
Mad Butthurt Syndrome is when someone loses their mind because something went wrong and they're too proud to admit it.
My mom got mad because I spilled coffee on her new dress. She screamed, 'You're gonna pay for that!', even though it was accidental.
My brother lost the game and started crying like a baby. He said, 'You're all cheaters!', even though he cheated.
My friend got mad because I laughed at her joke. She said, 'You're the worst friend ever!', even though it was a really bad joke.
