An extraordinarily large or voluminous bowel movement. Named in part for the comic-strip Great Dane, known for his extreme size, and in part for duke, a shortening of the fecal synonym dookie.
"Be careful in that stall man, someone took a massive marmaduke in there. It's filling like 75% of the bowl, and they clearly left it there out of pride. Or maybe the toilet just gave up."

1. A terrible comic, shown in many major newspapers. Has been known to ruin one's day just from a glance.

2. Anything that ruins a specific activity just from reading it.
Example 1:

Person #1 "I see you read todays Marmaduke"

Person #2 " how can you tell?"

Person #1 " you look rather depressed"

Example 2:

Every time I read her tweets it annoys me so much I close my twitter. She is such a Marmaduke
