The art of masterbating whilst having a poo at the same time. Preferably one should reach climax at the same time as they push out their poo.
But it is also poo masting if one poo's before they reach climax, or if they reach climax before they poo.
Ben was caught on the toilet poo masting.
He poo masted.
He is a poo masta.
