SDB

Abbreviation for silly duffer brother.

SDB can be used as a noun or adjective to describe an extremely idiotic person (also a nitwit or fool) or an extremely idiotic action.

SDB combines Aussie slang (silly duffer) and incorporates a reference to the world renowned Duffer Brothers (American twin brothers who write and direct science fiction films, horror films and television shows - including Stranger Things).
