McDookleberry
A slightly larger, more pungent and severe dingleberry that refuses to exit the anus.
I sat on a McDookleberry and ruined my favorite underwear, I knew I felt something after that last fart.
McDookleberries
The small end of a bowel movement, after a McDonald's meal as the rest refuses to pass through at the time.
I had a false alarm after my McRib lunch today... Only thing that came out was a couple mcdookleberries. But the bathroom was closed for 46 minutes afterwards...
