What foods cause tummy aches?

Are there any foods that cause loud gurgling tummy aches? Tomorrow is a girls bithday at my school and she hates me!!! She invited me to her party to make fun of me and make me look stupid. And my moms making me go!!! I need a tummy ache to get out of having to go. Btw last time she made someone go that she hated. She made a special piece of cake for her using roton eggs. The poor girl had a horrible stomach ache and had diarrhea and was throwing up all night.
