it's the new fad drinking game all the kids are playing, "Weasel Tar"
you get a whole mess of shit beer and pour it in such as a cistern or an elaborate vase
then mix in just, a rude amount of whole wheat flour
until it's basically a sludge or a paste
and then you all stand around it and put some into your cupped hands and consume it that way
i verified with them that it was not a prank and they did not go ii their homes later ii collectively laugh at me on the internet
