The scratchy, super low quality grey wool blankets that are
passed out to the
homeless at shelters and food banks. Some of them look like they've been puked on because of these random colored threads woven
throughout the blanket. These ones can also be called barf blankets.
My homie Les, who just recently got housing, used bum blankets as
decoration on the walls of his new tiny home. Others who are less
fortunate than my homie Les have been known to repurpose bum blankets as a urinal or toilet when
appropriate.
