Lithuanian Doughnut

The act of forcibly feeding a person to such an extent, that excretion is inevitable. The catch, however, is that prior to them defacating, you force their face upon their own rectum thus enabling them to consume their own feces. The Lithuanian doughnut is essentially a solo human centipede.

“Yo ur bacc ok fam?”
“Im in pain, but I really don’t mind. The Lithuanian doughnut was a worthwhile treat!”
