Mustard plug

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.

Mustard Plug

A small piece of hard (and sometimes crusty) shit that you push about before a big wave of diarrhoea.

That mustard plug was like a dam holding back a reservoir of shit, I just ruined my toilet.
