''Killer Nerd'' is a 1991 shot-on-video comedy horror film.

The plot of the film revolves around Harold Kunkle (Toby Radloff), a twenty-something nerd with an overbearing mother and a whole lot of bad luck. He tries, and consistently fails, to get a girlfriend and is also the target of bullies. Then one night, after being beaten down by drug dealers, Kunkle reaches his breaking point and goes on a killing spree, murdering those who have wronged him over the years.

The movie received a sequel the following year, known as "Bride of Killer Nerd."

Both films were soon distributed by Creator/{{Troma}}. You can view both movies [[https://www.youtube.com/watch?v=ShhENu0ZWQo here]] and [[https://www.youtube.com/watch?v=DcQDGfZqTwM here]].
