Last Night I Went To The Movies And Ate A

Last night I went to the movies and ate a ton of junk, like popcorn, candy, and soda. When I got home I kept pooping liquid. There were chunks of food in it, but it was mainly liquid. I have had a bad cold for the past week, but I'm not sure if the poop is due to the food I ate, or if it's developing into a stomach flu
