The Guy is a stereotypically nerdy man-child who has no life outside of his favorite media franchise. He still lives with his parents, and he doesn't attend college, nor does he have a job, and yet he is somehow entitled to an allowance.
Huey and Riley first met the Psycho Star Wars Guy when all of them were waiting in line to see The Phantom Menace at the local movie theater. The Guy had apparently been camping outside the box office, eagerly anticipating the new movie. But like most other Star Wars fans, he was angrily disappointed by The Phantom Menace. He decided to take Huey's (half-joking) suggestion to (literally) kick George Lucas' butt, remarking "May the Force of my foot always be with your backside!"
Despite his disappointment with the previous movie, he is later seen camping out to see the next Star Wars prequel film, Attack of the Clones. He has an awkward conversation with Huey about his undying devotion.
