I pulled a boner
When you pull a boner, you make a mistake so bad it makes your brain feel like it’s going to explode. It’s like when you forget to do your homework and then try to blame your cat.
I pulled a boner and told my brother I was going to be a dragon.
I pulled a boner and said I was going to live in a cave.
I pulled a boner and told my mom I had a secret power to turn invisible.
