Being in a state of amazement due to lack of/excessive bowel movements. (A play on 'dumbfounded')
When one has eaten plenty of roughage & fibre but is still unable to poo. Causing questionable surprise leaving them unpleasantly Dumpfounded.
Also used in the opposite as: When one has had a poor diet for a few days but still manages to produce a well-rounded, hefty dump. Causing an unexpected surprise but leaving them pleasantly Dumpfounded.
