The Duuuval Donut is a very intimate act bestir two lovers. In which, the male put a sprinkled donut on his erect Unit. He then proceeds to fuck partner in the ass excessively, said partner then consumes said donut, whilst performing fellatio and screaming Duuuval at climax.
I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
