I pooed myself on the last day of school! Really embarring...!?

you sound like you're telling a story. Anyway people are going to remember it and they will tell their friends about it as well. I'm sorry but that's just life. They're going to make fun of you or laugh at you and some might give you funny faces but you just have to walk away and don't say anything because if you do they'll tell you something bad and you'll feel worse. You can't do anything but just ignore them and sometimes it helps to laugh at yourself so you won't feel too bad or embarred and then people may no longer trouble you if it's not affecting you in any way if you're laughing. Good Luck
