A nerdgasm is a sudden, euphoric, blissful feeling brought on by mention or example of a deep abiding knowledge of all things nerd. Nerdgasms can be felt by any and all people with an honest and sincere interest in science fiction, sci-fi/fantasy, and heroic, writings, teachings, cinema, and television. Nerdgasms have also been known to occur in the act or conception of roleplaying, collectible card games, and eletronic games. Finally the last known cause of nerdgasms is the collection or viewing of rare or otherwise hard to find nerd memorabilia. Note: nerdgasms and nerds are not to be confused with geekgasms and geeks.
