A fan of Star Trek, aka Trekker, Alhough Gene Roddenberry once mentioned that the only word he acknowledged was Trekkie. Trekkies are commonly known for their unique behavior often memorizing everything there is to know about Star Trek, going too conventions, having every Star Trek episode on VHS or DVD. Mainstream Media often pokes fun at them for being geeks, nerds, or just freaks.

Orgins:
The Term Trekkie can be seen in the novel "the great trek" by E.A. Walker, of course at this point it had no relation whatsoever to Star Trek.
More than 30 years ago, A Science Fiction editor by the name of Art Saha applied the word Trekkies to Star Trek fans when he saw a group of Star Trek fans wearing pointed ears at a Science Fiction convention.

(n.) A fan, avid or otherwise, of at least one Star Trek series or movie. Devotees who totally immerse themselves in this subculture have given this term a somewhat negative stereotype, turning the majority of the fan base into the butt of many lame jokes. More "reality based" Trekkies, hoping to differentiate themselves from the habituous character-emulating, convention-attending crowd, choose to accept the label of "Trekker".
"John has the entire 3 seasons of the original Star Trek on DVD. What a Trekkie!"

"Nah... John's more of a Trekker. At least he doesn't go to half a dozen conventions a year dressed as a Klingon."
