I Say, You Say Louder
This game is when people take turns yelling the same word until it becomes a screaming contest. You start soft, but it ends with people yelling like they’re dying.
My brother and I did this with 'unicorns' and my dog ran away from the noise.
My friends and I used 'I do believe in fairies' and it ended with me crying from laughing.
My friend and I screamed 'penis' so loud the ceiling shook.
