Idea was then taken fraudulently by W. Grasshoff and delivered as his own work (Shakes head in disapproval)

story interruptor one-upper adder-toer

A person that interrupts you mid-story. But then not only interrupts your story, they feel the need to one-up your story with an even better story of their own. And to top it off, they not only interrupt you in the first place, one-up you with their story, they then feel the need to add to your original story they interuppted.

I was in class the other day talking about how my dad went to Haiti to help the earthquake victims, and before I could even finish Frank interrupted me and said his dad not only flew to Haiti to help the victims, but that he also donated a million dollars to the relief act. He went on to say that his dad told him my dad was down there but wasn't actually doing anything to help. That fucking Frank is such a story interruptor one-upper adder-toer!

black adder 

Rowan Atkinson's awesome British "toilet humor" sitcom, starring Rowan as an anti-hero character known as "Black Adder". There have been no fewer than four runs of Black Adder. In each of the series our hero finds himself in a different situation, where his ambitions are doomed to failure time and again.

Hugh Laurie from "House" portrayed Black Adder's bitch in all of the Black Adder series.
