Icing on the Cookie
It was my younger sisters first sleepover. My mom had made a ton of sugar cookies for my sister and her friends to decorate as an activity. I ate ALL the extra cookies.
Later in the night I started to feel really sick and headed towards my parents room. As soon as I got into the living room I threw up all over everyone. My sister never wanted to have a slumber party again. Story credit: Reddit / leebins
