Factination
Factination is when you tell a story so many times it turns into a lie. You add stupid details and make yourself look like a hero. It's like when you tell the same story to your grandpa 10 times and it gets wilder every time.
My mom told the story of my birth 10 times, and now I was born in a spaceship.
My dad said he fought a bear. Now it's a whole saga with a bear, a sword, and a bear sword fight.
My sister said she got a perfect score on her test. Now she says she aced it with a bear and a sword.
