Nerd-orgy 

The wondrous sensation of visiting the Wizarding World of Harry Potter, specifically in Florida.

Dude! It was a total nerd-orgy there!

Nerdorgy 

Is when a group of nerds get together for any kind of convention or party.

A hot group of A-list nerds hanging out.

Hey Jane, I just got invited to a Star Trek convention and a renaissance fair on the same weekend! Which nerdorgy should I go to?
