Get the Mustard Plugged mug.
A small preliminary shit that, once expelled, gives way to a large volume of feces. It resembles and reminds one of the crust of dried mustard that forms on the cap of the bottle which must be voided before the main mass of the condiment can be squeezed out.
Jason: "How's your stomache ache, bro?"
Matt: "It's gone now. I had a thick mustard plug that was blocking a giant diarrhea bomb."
Jason: "Gross dude!"

Get the Mustard Plug mug.
A small amount of solid poop holding back diarrhea like the small amount of hard mustard in the top of a mustard container.
I sat down on the toilet and the mustard plug pooped out then was followed by explosive diarrhea.
