Uhdubladah 

An adjective yelled out in excitement on the south shore part of Massachusetts. Usually when a friend pops out of nowhere. It is very commonly used even though popular belief suggests that it has never been heard of by human ears.

As curious George roamed the hallway, his owner ,Niggbo Dacious, finally found him in the lounge. In excitement he yelled "uhdubladah!".
