scrumptious; delectable; similar to “delicious”; usually used to describe brown explosions, greased goosling, fresh baked bread, and any red colored liquid
i.e.: "I'm feeling a little dumptious." or "begging your pardon ma'am, but my guts are full of chimichanga and I'm quite dumptious at the moment." or "I'm sure what you're telling me is really important but I'm too dumptious to give a shit."
A person who is a dufus but also delicious. That guy we met isn't the smartest, but he sure is duflicious! I'd sleep with him in a heartbeat but hope he doesn't speak. He is a dufus and delicious.
To be deliciously not bright.
