When someone vomits inside a womens vagina and closes it back up for the next man to eat out. then that man shits in her vagina to make it worse smelling. Than finally, she squeezes it out into a paper bag to give to her boyfriend, who has just been cheated on twice.
Bob: oh fuck!!!
Andy: What happend!
Bob: my girl, just gave me a chunky lunchbox
Andy: oh that sucks
Bob: i had a feeling she was cheating.
