bimbleedoo 

A person one has been seeing, i.e. someone you are involved with in a non-exclusive relationship (often prior to boyfriend/girlfiend status)

My bimbleedoo will never be my bird because she always has gravy stains on her knickers.

bumbledoofus 

A person who is lost and without adequate intellectual resources.

Although blessed with a winning smile, he has always been a complete bumbledoofus.
