Zappanasta 

A person that knows every line up of all of the band members on any recording that Frank Zappa ever performed on, wrote, or produced.

They also know all of the written lyrics and the lyrics and variations of how the song was actually performed live.

I was humming along to Yellow Snow and put a 'Wee Wee" in the wrong place and was immediately corrected by a Zappanasta.

Zappacosta 

1. n. - Species of apelike mammal, quite possibly the missing link between Australopithecus and Homo Erectus, common to suburban Delaware and characterized by heavy body odor, unnatural slow wit and a diet primarily comprising Skittles and Easy Cheese. Prone to hyperactivity at the sight of nude nubile human females.

2. slang - Any person who is allowed to exist in polite society when he should rightly be remanded to an orphanage for the mentally handicapped.

Various state and federal laws kept the docile yet dysfunctional Zappacosta from being institutionalized; rather, he passes his idle days chewing his own cud on a quiet Delaware lawn.
