A Michael Bay (named after the film director/producer) is a term used to describe a solid excretion that starts off pleasant but continues for so long that it causes the excreter to lose interest, or in some cases, physical pain, essentially like sitting through a Michael Bay film or Michael Bay marathon, you're feeling good about the first ten minutes or so but then you slowly lose interest and/or it physically hurts to carry on.
"I'm off to the loo"
"I hope it's not a Michael Bay."
"You were gone a while."
"Yeah, it turned out to be a Michael Bay, one of the most painful half hours of my life"
