When you take a
poop and think you're finished, but your body's
like "BUT WAIT, THERE'S MORE," similar to a Billy Mays infomercial.
Sometimes
may manifest as a poop lasagna.
Person A: "You were in there for
like 20 minutes and it reeks!"
Person B:"Sorry, I had a Billy
Mays poop."
Person A: "Damn, those are the worst."
