Phi psi poopy chest??

I was drinking maybe a litttllee tooo much with my girls one night at phi psi a few months ago. What I thought I saw was very gruesome. It appeared to be some of the older guys in the house, pants dropped, taking turns pooping on the pledges chests while they lay on the floor. I quickly got rushed out by one of my guy friends and he told me it was a joke for a tik tok. Now this whole thing makes more sense with the hammers. Do they do poopychest to everyone? Has anyone heard of this?
