Get the Hollow Poop Fart (HPF) mug.
when you sit down on the toilet expecting a massive deuce and instead have a massive, loud, airy fart, which feels like it has enough power to part the waters below
I couldn't hold in my laughter this afternoon when I was sitting on the toilet and heard a massive hollow poop fart (HPF) come from the stall next to me.
