A bra made of poop, most commonly dog poop, that is usually acquired accidentally when creating a snow angel while nude.
Kenzie: I want to go make a snow angel while nude.
Onlookers: watch out for the mega dump the dogs took.
A few minutes later:
Onlookers: oh my god Kenzie found the mother load and has a poop bra now. Oh my god she is now vomiting and looks like a homeless person in the yard.
