What is ghost poo?
Ghost poo is what my son calls those white peanut things that is used for packing filler. Works for me.
It is ghost fecal material. It is white, small, looks like bits of styrofoam and comes packed in most boxes you receive. It is full of static and sticks to everything; goes all over the floor. Look under just about any bed in your house where you've unpacked any kind of order and you'll probably find a few "stools" of it.
