A box (cardboard or storage bins) used to put our stuff/prized possesions/collectables/valuables in. Poo box can be big or small depending on how much stuff you have. You can one or several of them of any size.
Person 1: I have a lot of little stuff. I need a poo box for it. I also have more stuff in my closet that needs to be put away neatly. I don't wanna lose any of this stuff. I think I need to go to Target and get some poo boxes from the home storage isle.
a slang frase used for descrbing a woman's/man's ass!!!
did you see the size of that poo box that just walked by...
