look up any word, like blumpkin:
 
1.
A person who's favorite things consist of: Star Trek, Star Wars, any type of Nintendo, Playstation, or computer game, and star trek/star wars conventions.

Space nerds can quote any star wars movie on command and live in their parent's basement collecting pieces of dust balls that resemble Luke Skywalker or Lara Croft.

You can find a space nerd at the opening of any Star Wars movie, and they will most likely be wearing a Chewbacca outfit as they ruin the whole movie for everyone else by reciting every single line in the movie.
That space nerd keeps making claims that he is acually Luke Skywalker.
