A foot long
A foot long is a piece of poop so long, it could be used as a measuring stick. It's 12 inches and two inches thick. If you're lucky, it might even have corn in it.
My foot long was so long, my sister measured it with her phone.
After my foot long, my mom said, 'You ate the whole menu.'
My foot long had corn in it. I asked, 'Did you eat the corn or the sandwich?' She said, 'Both.'
