When a girl has diarrhea and shits herself and you let it dry and then put grape jelly around her anus and eat it out while watching the sunset on the beach

Guy: I’m hungry asf!
Girl: do you want a east coast uncrustable?
Guy: oh shit yeah I have some grape jelly in my bag!
Girl: ok hehe well I just shit all over myself and it’s crusted over

Guy: perfect and suns just setting!
