Dumb and Dumber Shit
Inspired by the movie "Dumb and Dumber " when Jim Carrey's character gives Jeff Daniels character a large amount of laxatives to ruin a date. It lead to Daniels sitting on the toilet talking a very noisy, smelly shit. Dumb and Dumber shits often come after a thunderous stomach growl in which the person knows it is time to get to the toilet.
"That mexican food was great last night, but I feel a "Dumb and Dumber Shit" coming on."
